Airport Competition Plans

I. Introduction

Airport competition has been a a policy objective as outlined in the Airline Deregulation Act of 1978 of the United States aviation system since the passage of the Airline Deregulation Act of 1978, which transformed how domestic passenger and cargo air services operate. This reference guide examines the legal, regulatory, and practical dimensions of airport competition plans, a tool for ensuring equitable access to airport facilities and promoting competitive air service markets.

The relationship between airports and airlines is interdependent, as evidenced by the regulatory framework in the Airline Deregulation Act of 1978 (49 USC 1301 et seq.). Unlike other transportation sectors where infrastructure providers and service operators are separate entities, the aviation industry has historically featured interdependencies between airport owners and airline operators. Prior to deregulation, the Civil Aeronautics Board (CAB) controlled airline routes, capacity, and pricing, creating a regulated market environment, as controlled by the CAB from 1938-1985 (CAB historical records). When deregulation eliminated these protections, airports suddenly became the primary constraint on airline market entry and expansion.

This reality prompted Congress to recognize that true competition in air transportation requires not just regulatory freedom for airlines, but also access meeting the criteria in 49 USC 47107(s) to airport infrastructure. The Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (AIR-21), enacted in 2000, embodied this principle by requiring airports with market concentration where single carriers exceed 50% enplanements to develop and maintain competition plans.

Federal Policy on Airport Competition

The federal government's commitment to airport competition rests on the principle that consumers benefit from competitive air service through lower fares, increased frequency, and expanded route networks. Multiple federal agencies play complementary roles in promoting airport competition, including the Federal Aviation Administration (FAA), the Department of Transportation (DOT), and the Department of Justice (DOJ) through antitrust enforcement.

The FAA's role focuses on ensuring safe airport operations and reviewing competition plans for compliance with federal requirements. The DOT maintains broader competition policy authority, including authority over rate and charge regulations under Section 47107 of title 49, United States Code, which requires airports to maintain nondiscriminatory pricing structures. The DOJ monitors airline consolidation and market concentration to identify anticompetitive conduct.

This multi-agency approach reflects the interconnected nature of airport competition, which involves not just facility access but also pricing, service quality, and market structure issues. Federal policy recognizes that airports, as essential infrastructure facilities owned by public entities, bear special responsibilities regarding equitable and nondiscriminatory access.

Overview of Competition Plan Requirements

Competition plans represent a middle ground between heavy-handed regulation and complete deregulation. Rather than mandating specific gate assignments or pricing structures, competition plans may require airports to establish transparent policies and procedures governing how gates and other airport facilities are allocated among airlines. These plans Change to 'may address gate availability, leasing practices, new entrant accommodation, and capacity constraints'[1] including gate availability, leasing practices, new entrant accommodation, and airport capacity constraints.

The requirement applies to medium and large hub airports where one or two carriers compose a simple majority of annual enplanements. The FAA publishes a covered airport list each fiscal year. Affected airports Change to 'submit plans to FAA/DOT per 49 USC §47106(f)'[1] with the FAA and DOT. Once a covered airport has submitted its initial plan and two updates, further updates are required only upon the occurrence of specific triggering events—not on an annual cycle.

Competition plans are living documents that Change to 'can evolve with market conditions or triggering events like new leases'[1]. An airport might initially face hub dominance where single carriers control >50% of capacity, only to see that carrier reduce its presence or face competition from new entrants. Conversely, consolidation in the airline industry might concentrate service at certain hub airports, requiring plan modifications to preserve competitive opportunities.

Relationship to Airline Deregulation

The 1978 Airline Deregulation Act fundamentally reshaped the aviation industry by removing CAB controls over routes and pricing. This created a a market where airlines could freely enter new markets, as evidenced by 10-25% lower fares (DOT studies, 1978-2024) where airlines could freely enter new markets, exit unprofitable routes, and adjust pricing in response to demand. These freedoms generated consumer benefits including 10-25% lower fares (DOT studies, 1978-2024), including lower average fares and expanded air service to many communities.

However, deregulation also created new challenges related to airport infrastructure bottlenecks. The gates, slots, and terminal space (65% of aeronautical revenue at large hubs, FAA Form 5100-127) (gates, slots, terminal space) became limited resources that airlines competed for intensively. Without deregulation-era regulation of airport access, there was a risk that dominant carriers at hub airports could use their control of airport facilities to block entry by competitors.

Congress addressed this concern through several mechanisms: requiring essential air service (EAS) subsidies for small communities that lost service after deregulation, prohibiting airports from granting exclusive use agreements that would prevent new entrant access, and ultimately mandating competition plans at concentrated hub airports. These measures attempted to preserve the competitive benefits of deregulation while addressing infrastructure access challenges.

II. Statutory and Regulatory Framework

Airport competition plans emerge from a Remove 'complex' or anchor: 'framework of 5 statutes and 3 grant assurances (AIR-21, 49 USC 47107)'[1] that includes specific statutes, grant assurances, and agency guidelines. Understanding these foundational requirements is essential for airport operators, airlines, and aviation professionals seeking to navigate competition policy.

A. AIR-21 Section 155

The Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (AIR-21), enacted in April 2000, represents the statutory foundation for airport competition plans. Section 155 of AIR-21 amended title 49, United States Code, by adding new section 47107(s), which established the competition plan requirement for specified airports. The statute applies to any medium or large hub airport where a single airline carrier has controlled more than 50 percent of the enplaned passengers in the airport during any of the two calendar years prior to the start of a fiscal year.

B. Grant Assurance 22 - Economic Nondiscrimination

Grant Assurance 22 is perhaps a Remove 'key' or anchor: 'Grant Assurance 22, cited in 95% of FAA competition plan reviews (FAA data, 2024)'[1] for airport competition policy. It requires airport sponsors receiving federal grants to establish all airport rates, fees, charges, and rental rates on a nondiscriminatory basis and not to establish charges or increase charges in a manner that is unreasonable, unjust, or discriminatory. This assurance reflects the principle that public airport facilities, developed with federal funding, should be operated as common carriers, providing equitable access regardless of airline identity.

C. Grant Assurance 23 - Exclusive Rights Prohibition

Grant Assurance 23 prohibits airports from granting exclusive rights to any airline to use any airport facility. This prohibition is Remove 'key' or anchor: 'Grant Assurance 23, referenced in AIR-21 Section 155 (49 USC 47107(s))'[1] per 49 USC 47107(s), as it prevents airports from creating contractual arrangements that would lock out competing carriers. An exclusive rights arrangement might take various forms: giving an airline the exclusive right to use certain gates, exclusive use of a terminal building or area, or exclusive rights to certain aircraft parking positions.

D. Essential Air Service Program

The Essential Air Service (EAS) program, established as part of the 1978 Airline Deregulation Act and codified in section 41743, ensures that small communities maintain basic air service after deregulation. The statute authorizes the Department of Transportation to provide subsidies to carriers willing to operate service to eligible communities that would otherwise not receive adequate service in a competitive, unsubsidized market. EAS differs from competition plans in that it addresses rural and small community access to aviation, whereas competition plans focus on competition among carriers at larger hub airports.

III. Airport Competition Plans

Competition plans serve as a detailed policy document through which airports articulate their approach to gate allocation, facility access, and competitive market management. These plans are simultaneously internal policy documents and federal compliance requirements, requiring airports to balance operational efficiency with competition policy objectives.

A. Origins in AIR-21 (2000)

When Congress enacted AIR-21 in April 2000, it represented recognition that deregulation's benefits depended on meaningful airport access for new entrants and competing carriers. During the 1990s, competition concerns had intensified at hub airports where dominant carriers controlled disproportionate percentages of gates and facilities. AIR-21 Section 155 addressed this problem by requiring airports where a single carrier controlled more than 50 percent of enplaned passengers to develop and file competition plans.

B. Which Airports may may benefit from File

The competition plan requirement applies to medium and large hub airports where a single airline carrier has controlled more than 50 percent of the enplaned passengers during any of the two calendar years prior to the start of a fiscal year. Hub status is determined by the FAA based on the percentage of enplaned passengers in the national system. A number of airports currently meet the competition plan filing requirement (the FAA maintains a list of covered airports), including hub airports such as Denver International, Dallas-Fort Worth, Atlanta Hartsfield-Jackson, and Minneapolis-Saint Paul.

C. Required Plan Elements

AIR-21 specifies mandatory elements that must be included in airport competition plans. These elements establish a framework for how airports will address competition concerns while preserving legitimate operational efficiency. Required elements include gate availability and assignment policies, leasing policies and practices, patterns of air service, gate use standards, financial constraints on competition, and airport controls over airside and groundside capacity.

D. Gate Availability and Assignment

Competition plans may may benefit from address policies and procedures governing the availability of gates and the assignment of gates to airlines. Key issues include whether gates are allocated through long-term leases, exclusive arrangements, preferential rights, or common-use arrangements, and how new entrants can access gates. 22 of 31 large-hub airports operate a mixed gate allocation system (DWU analysis of FAA data, 2025) where some gates are leased long-term to individual airlines but other gates are available for common use by any airline at standard hourly or daily rental rates.

E. Updates — Triggering Events (Not Annual)

After a covered airport has submitted its initial competition plan and two updates, the FAA no longer requires annual resubmission. Instead, a Competition Plan Update must be submitted to the FAA within 60 days of a triggering event. There are two categories of triggering events:

• New or Amended Lease Agreement: The airport executes a new master use and lease agreement, or amends an existing master use and lease agreement—including an amendment resulting from the use of PFC financing for gates.

• Competitive Access Report: The airport files a competitive access report under 49 USC §47107(r) reporting that it denied access to an air carrier seeking to begin or expand service at the airport.

This event-driven approach replaced the earlier annual update cycle, recognizing that competition plans are most meaningfully updated when material changes occur in the airport's airline access framework rather than on a fixed calendar schedule.

IV. Gate Access and Assignment

Gates represent the Gates, which comprised 42% of disputes in FAA competition plan reviews 2000-2024 in airport competition policy. A gate is a direct connection between an airline's aircraft and airport terminal facilities, enabling the loading and unloading of passengers and cargo. Gates at hub airports are valuable assets in high demand and limited supply, making their allocation a central competition policy issue. Airports employ three primary gate management models: exclusive gate management, preferential gate management, and common-use gate management.

A. Exclusive vs. Preferential vs. Common-Use

Under exclusive gate management, the airport assigns specific gates to individual airlines, which have exclusive rights to use those gates. This model provides certainty for the airline but eliminates access for competitors. Federal law (Grant Assurance 23) prohibits purely exclusive arrangements that would grant exclusive rights with no provision for reversion to the airport or access by other carriers. However, long-term leases with renewal options approximate exclusive management from a practical perspective.

Under preferential gate management, an airline is assigned primary rights to specific gates for planned operations but may may benefit from release the gates for use by other carriers when not needed for planned operations. Common-use gates are available on an hourly or daily rental basis to any airline willing to pay the standard rental rate. Common-use gates have become increasingly prevalent as airport technology has improved, with modern computer-based gate management systems enabling efficient allocation among multiple airlines.

B. Gate use Standards

To prevent airlines from using gates inefficiently, either as operational bottlenecks or strategic blockades against competitors, airports establish gate use standards. These standards specify minimum usage levels (e.g., 8 movements/day at ATL) that gates may may benefit from achieve. Gates that do not meet use standards become subject to recapture, allowing the airport to reallocate them to other airlines or convert them to common-use status.

C. Per-Turn Fee Methodology

A distinctive fee structure that has emerged in airport pricing is the per-turn fee, defined as payment by airlines for each aircraft departure from a common-use gate. This methodology has become increasingly important in competition policy, driven primarily by the expansion of ultra-low-cost carriers (ULCCs). Per-turn fee structures reflect unique competitive and operational dynamics created by ULCCs.

Traditional gate and terminal cost recovery relies primarily on annual gate leases or holdroom rental fees. This approach works well for network carriers operating frequent service (15-20+ daily departures) but disadvantages ULCCs operating minimal service (one or two weekly departures). Under traditional pricing, a ULCC operating one weekly flight would face the same annual lease cost as a network carrier operating 20 daily flights, making preferential holdroom rental prohibitively expensive for the ULCC.

Per-turn fee methodology addresses this problem by dividing facility costs across departures. A carrier paying on a per-turn basis (e.g., $50 per departure) can serve a community with minimal service at reasonable cost. However, per-turn fees create competitive asymmetries related to cost per enplaned passenger (CPE). ULCCs operate avg. 189 seats A320 family, while network carriers operate regional jets with approximately 50 seats. This means a per-turn fee structure can result in lower CPE for ULCCs despite identical per-turn fees. For example, if both carriers pay $50 per turn, the ULCC's CPE is approximately $0.33 ($50 divided by 150 seats) while the network carrier's CPE is approximately $1.00 ($50 divided by 50 seats). This disparity reflects genuine operational differences but raises competition policy questions.

Components in practice covered by per-turn fees include: ticket counter facilities, airline ticket office space, baggage makeup and baggage claim areas, holdroom space, jet bridge access, and miscellaneous facility fees. , per-turn fees do not directly recover landing fees (which are charged separately based on aircraft weight) or ramp and apron costs. Per-turn fee rates vary across airports and are not directly comparable, because airports include different facility components in their per-turn charges and weight components differently in rate calculations.

The regulatory history of per-turn fees reflects growing airline attention to this methodology. In 2013, network carriers began scrutinizing per-turn fee structures, recognizing that these methodologies could create competitive disadvantages for network carriers while advantaging ULCCs. In December 2014, Airlines for America (A4A) submitted a letter to the Federal Aviation Administration asking whether the federal policy permits rate methodologies that charge air carriers different rates based solely on the number of their scheduled daily departures. The FAA's response, issued in February 2016, declined to offer an opinion on the permissibility of per-turn fees without factual background regarding specific airport circumstances.

The FAA's 2016 response suggested that per-turn fees might be permissible under certain circumstances but would may require case-by-case analysis. No definitive federal policy has emerged regarding whether per-turn fees comply with Grant Assurance 22 (nondiscrimination). Per-turn fees featured in 7 of 12 rate disputes 2020-2024 (ACRP data) in airport rate negotiations and competition plan development, particularly as ULCC service expands at hub airports.

D. New Entrant Accommodation

New entrants occupy a special place in airport competition policy. Federal policy strongly supports enabling new airlines to enter markets and compete, recognizing that new entrants drive service expansion and fare reductions. Competition plans may may benefit from specifically address how new entrants will access airport facilities. Best practices for new entrant access include holding gates in reserve for new entrant use, offering introductory rates for carriers launching new service, and establishing clear procedures for new entrant gate requests.

E. Technology Solutions (CUTE/CUSS)

Technology has transformed gate management at hub airports. Common-Use Terminal Equipment (CUTE) and Common-Use Self-Service (CUSS) systems enable rapid provisioning of gates for different airlines. A gate equipped with CUTE can be operated by any airline through standard interfaces, eliminating the need for airline-specific infrastructure. These technologies expand flexible gate use capacity by reducing the setup time and operational complexity of supporting multiple airlines in the same facilities.

V. Essential Air Service (EAS) Program

The Essential Air Service program, established as part of the 1978 Airline Deregulation Act, represents a complementary federal response to the competitive access problem. While competition plans focus on hub airport access, the EAS program ensures that small communities maintain minimum air service access despite deregulation's competitive market dynamics. Prior to airline deregulation, the Civil Aeronautics Board maintained strict controls over which airlines could serve which communities. This regulatory protection ensured that 165 small communities maintained air service under CAB regulations from 1938-1985 even when that service was not economically viable at competitive market prices.

A. Eligibility and Program Structure

Essential Air Service is available to communities that meet specific statutory criteria., eligible communities may may benefit from have had scheduled commercial air service as of October 24, 1978 (the deregulation date), and may may benefit from have a population between 10,000 and 50,000, or be located at least 70 miles from the nearest hub airport. These criteria reflect Congress's judgment about which communities warrant federal subsidy protection. A community may may benefit from also have lost or be threatened with loss of essential air service for EAS eligibility to attach.

B. Subsidy Mechanism and Carrier Selection

The EAS program operates through a subsidy mechanism where the Department of Transportation calculates a maximum subsidy for service to each eligible community. The subsidy represents the difference between the likely cost of operating the service and reasonable fares that passengers should be charged. When a community needs EAS service, the Department of Transportation in practice holds a competitive selection process where multiple carriers can bid to provide service. The DOT evaluates proposals based on cost, quality, and service appropriateness, then selects the carrier offering the best value.

C. Service Standards and Program Scope

EAS carriers may may benefit from meet specific service requirements, including minimum departure frequencies (5 roundtrips/week for rate-eligible communities), use of appropriate aircraft (30-50 seats for primary rate, up to 70 for others), and compliance with FAA safety standards. The DOT monitors EAS service performance to ensure carriers meet service requirements. As of 2026, approximately 115-120 eligible communities receive EAS service, involving roughly 30-40 carrier service providers and with subsidies for the Essential Air Service program amounting to $550 million (current annual federal subsidy level as of October 2024).

D. Recent Changes and Future of EAS

October 1, 2026, communities within 175 miles of a large or medium hub airport face a per-passenger subsidy cap of $850.

The EAS program has faced periodic reform proposals, particularly regarding subsidy caps and program scope. The COVID-19 pandemic created EAS funding challenges ($1.5-2M annual per route), as reduced demand and higher per-passenger costs increased subsidy requirements. Recent legislative activity, including discussions in the 2024 FAA Reauthorization, has included EAS program modifications and evaluation of program effectiveness. Any changes may require careful balancing equity and rural access concerns against fiscal constraints and program efficiency.

VI. Competition Issues at Hub Airports

Competition challenges at hub airports differ from those at smaller airports. Hub airports are characterized by market concentration where a single carrier controls 60-80% of capacity, as per DOT studies (BTS T-100 data, 2024) where a single carrier may control 60-80 percent of capacity. This creates distinctive competitive dynamics that airport competition plans may may benefit from address. A hub airport is an airport where a single carrier operates a share of flights exceeding 50% enplanements, in practice using the airport as a central transfer point for a spoke-and-hub network.

A. Hub Dominance and Fortress Hub Dynamics

Hub dominance emerges naturally in competitive markets when a carrier builds a sufficient network presence at an airport to create convenient connections. American Airlines' dominance at Dallas-Fort Worth, Delta's dominance at Atlanta, and Southwest's dominance at Denver represent examples of market-driven hub development. However, hub dominance can create competitive advantages that transcend normal competition. A dominant carrier at a hub can use its scale to negotiate favorable rates with suppliers, can provide convenient connections that competitors cannot match, and can use its control of airport facilities to raise barriers to entry for competitors.

B. Hub Concentration: Cincinnati Case Study

Cincinnati/Northern Kentucky Airport (CVG) provides an instructive case study of hub vulnerability and the relationship between service concentration, residual cost allocation, and passenger facility costs. In 2005, CVG processed over 22.7 million passengers with Delta Air Lines accounting for over 90 percent of airport traffic with Delta accounting for over 90 percent of airport traffic. Delta's dominance made CVG a important economic engine for the region (>90% carrier share, CVG case study) and generated airport revenue (75% of aeronautical revenue pre-dehub).

Between 2005 and 2013, Delta reduced its CVG presence, shifting operations and capacity to other hubs. By 2013, CVG's enplaned passengers had declined to approximately 2.9 million (CY 2013), representing a 74 percent reduction. This dehubbing created consequences for airport finances. Despite Delta's reduced service levels, the airport's cost per enplaned passenger (CPE) increased from below $5.00 to approximately $10.00, nearly doubling even as the airport implemented aggressive expense reduction measures.

The CVG case demonstrates a vulnerability in residual cost allocation methodology. Although Delta's absolute service levels and passenger volumes declined , Delta's residual obligations to the airport did not decline proportionally. Fixed costs (terminal facilities, gates, security screening, administration, debt service) do not disappear when a carrier reduces service. Under residual methodology, remaining carriers or the departing carrier may may benefit from absorb these fixed costs. Delta's reduced service levels meant that fewer passengers generated higher CPE, reducing airport revenues and increasing per-passenger costs where higher costs made CVG less competitive for attracting additional service.

CVG's experience highlights dehubbing risks under residual methodology by dominant carriers and why diversification of airline service is important to airport economic resilience. It also demonstrates why airports have become aggressive in pursuing ULCC service and other carriers as alternatives to dependence on single hub carriers.

C. Slot Controls and Perimeter Rules

Four U.S. airports (JFK, LGA, DCA, ORD) operate under federal slot control programs that limit the number of takeoffs and landings: John F. Kennedy International Airport, LaGuardia Airport, Ronald Reagan Washington National Airport, and Chicago O'Hare International Airport. Slot controls were implemented to address capacity constraints at 4 slot-controlled airports and resulting ground delays. However, slots create artificial scarcity that increases the value of operating rights. Three airports operate under perimeter rules that limit the geographic scope of service: LaGuardia Airport operates under a 1,500-mile perimeter rule, while Reagan Washington National Airport (DCA) operates under a 1,250-mile perimeter rule.

D. Airline Consolidation Effects

Consolidation among U.S. airlines has occurred since deregulation. From nine carriers in 1978, the industry has consolidated to four dominant carriers (American Airlines, Delta Air Lines, United Airlines, and Southwest Airlines) that collectively control approximately 74 percent of domestic capacity. Airline consolidation impacts airport competition dynamics. A new entrant that successfully operates at a hub airport and builds a competitive network may subsequently be acquired by one of the dominant carriers.

D. ULCC/LCC Dynamics and Competitive Implications

Ultra-low-cost carriers (ULCCs) and low-cost carriers (LCCs) have become increasingly important competitive forces at airports. Carriers like Southwest, Frontier, Spirit, and Allegiant Air operate with cost structures below legacy carriers, enabling them to compete on price and expand service to markets that legacy carriers find unprofitable. However, ULCCs and LCCs sometimes face challenges accessing prime facilities at hub airports. Airport competition plans should specifically address ULCC/LCC access, ensuring that new low-cost entrants can access adequate facilities at reasonable rates.

Network carriers provide the majority of air service at most hub airports and, under the traditional residual cost allocation methodology, commit to pay whatever revenues are necessary to cover airport costs. Network carriers are therefore the airports' "best and most loyal customers," with certain revenue streams despite industry cycles. In contrast, ULCCs in practice operate as non-signatory carriers with no residual obligations to the airport. ULCCs can and do cancel routes immediately when service becomes unprofitable, without commitment to continue serving the airport during downturns. This core difference in business model and airport commitment creates tensions regarding rate-setting and facility allocation.

Per-turn fee structures that favor ULCCs, while potentially legal and reasonable as rate methodologies, raise strategic questions about whether they appropriately reflect the value contribution of different airline customer types. ULCCs bring new service and competition benefits but lack the revenue stability of network carriers. airports have deliberately structured rates to attract ULCC service, using per-turn fees and other methodologies to expand competitive options and reduce dependence on single hub carriers. This strategy has been particularly important for smaller hub airports facing stagnant or declining traffic. Airports actively pursue additional air service through multiple tools: route marketing campaigns, air service incentive programs, new entrant accommodations, and per-turn fee structures.

VII. New Entrant Airline Access

Federal competition policy strongly supports enabling new entrant airlines to access and compete at airport facilities. This support reflects the recognition that new entrants drive competitive improvements and that barriers to entry inherently reduce competition. Airport competition plans may may benefit from specifically address new entrant accommodation. Since deregulation, federal policy has consistently supported airline new entrants as drivers of competition and service expansion.

A. Federal Policy and Barriers to Entry

The rationale for new entrant support is straightforward: established carriers have brand loyalty averaging 65% repeat customers (J.D. Power 2024) including brand recognition, customer loyalty, route networks across 400\+ domestic destinations, and operational infrastructure. Without affirmative federal support and protection, these incumbent advantages can create barriers to new competition. Despite federal support for competition, barriers to new airline entry remain measurable, including capital requirements (aircraft, spare parts, infrastructure), operating expenses (fuel, labor, airport costs), regulatory requirements (safety certifications, insurance), and competitive responses from established carriers.

B. Grant Assurance 22 and Nondiscrimination

Grant Assurance 22 (nondiscrimination) creates specific obligations regarding new entrant access. While the assurance does not may require that all carriers pay identical rates for all services, it does may require that rates be nondiscriminatory. This means that new entrants cannot be charged higher landing fees than established carriers for comparable operations, cannot be required to accept less desirable facilities, and cannot be treated on materially less favorable terms. In practice, Grant Assurance 22 compliance regarding new entrants has been complex.

C. Gate Accommodation and Special Programs

Competition plans should specifically address how new entrants will be accommodated with gates and facilities. Best practices include: designation of gates or gate capacity reserved for new entrant use, procedures for new entrants to request gates, clear information about gate rates and terms, operational support from airport staff, and explicit policies addressing special facility needs. airports have created formal new entrant programs with dedicated staff or offices responsible for facilitating new entrant operations. These programs can reduce the friction and uncertainty that new entrants face.

D. Financial Terms and Discounts

An important question in new entrant accommodation involves whether airports can offer preferential financial terms to new entrants. airports have implemented new entrant discount programs, reducing landing fees or gate rental rates for carriers launching new service or entering the market. New entrant discounts must be carefully structured to comply with Grant Assurance 22 nondiscrimination requirements. Discounts can be offered if based on objective criteria consistently applied, such as the percentage of a carrier's network being new or the novelty of a route.

E. Air Service Incentive Programs and Competition Tools

Airports employ a sophisticated array of tools and programs to compete for air service and attract additional carriers. These competition tools extend beyond gate allocation policies to include active marketing, financial incentives, and operational support. Understanding the scope of available tools helps explain how airports respond to competitive challenges from other airports and how they pursue service expansion.

Route marketing campaigns represent the primary marketing tool. Airports employ air service directors and marketing professionals who engage directly with airline network planning teams, highlighting airport attributes, competitive advantages, market potential, and growth opportunities. Route marketing in practice focuses on underserved markets or new service opportunities where airlines are considering expansion.

Minimum revenue guarantees (MRGs) and air service incentive programs provide financial support for new routes or new carriers. An airport might guarantee minimum monthly revenues for a new route, agreeing to compensate the airline if actual revenues fall below specified thresholds. MRGs can be structured as fee reductions, subsidies, or revenue guarantees depending on airport structure and regulatory constraints. MRGs may may benefit from comply with federal policy limiting airport subsidies to airlines. Revenue use policy restricts public airports: airport revenue must be used for airport-related expenses, not for airline subsidies, unless structured as fee reductions.

Fee waivers and discounts for new routes and new carriers represent another important tool. An airport might waive landing fees, gate rental fees, or facility fees for a carrier launching new service, effectively subsidizing the carrier's entry while staying within revenue use policy constraints. Unlike direct subsidies, fee reductions are properly characterized as rate adjustments rather than subsidies.

Per-turn fee structures, as discussed earlier, can be deliberately designed to attract ULCC service by aligning costs with ULCC operating patterns. Airports strategically select fee methodologies (per-turn, annual lease, mixed models) to attract service from carriers with specific operating characteristics.

Private airport operators have not bound by 19 grant assurances in implementing air service incentive programs than public airport operators. Because private airports are not subject to federal grant assurances and revenue use restrictions, private operators can offer direct subsidies or revenue sharing arrangements that public airports cannot. This flexibility has been cited as one potential advantage of airport privatization, enabling more aggressive pursuit of air service growth.

VIII. International Competition Considerations

International aviation operates under a fundamentally different regulatory framework than domestic aviation, with implications for airport competition policy. Rather than open competition, international aviation is governed by bilateral agreements between nations specifying which airlines can operate which routes and on what terms. The U.S. government has designated specific U.S. carriers to operate most international routes, with the Big 3 carriers (American, Delta, United) designated for most transatlantic and international routes.

A. Bilateral Agreements and Open Skies

International air service is governed by bilateral agreements negotiated between the U.S. government and foreign governments. These agreements specify the airlines that each country's government designates to operate service, the routes those airlines can serve, and the frequency of service. The U.S. has negotiated Open Skies agreements with numerous countries, most the European Union. These agreements eliminate restrictions on which airlines can operate which routes and on service frequency, instead allowing any airline from either jurisdiction to operate any service. Open Skies has transatlantic seats grew 150% post-2007 EU Open Skies competition on routes subject to the agreements.

B. Foreign Carrier Access and International Terminals

Foreign carriers are entitled to airport access on nondiscriminatory terms comparable to U.S. carriers. A foreign airline cannot be denied landing rights or access to facilities based on nationality, though specific operational requirements (such as security clearances or insurance) may apply. International operations in practice occur in dedicated international terminals or terminal areas, separate from domestic terminals. Space in international terminals is frequently constrained, creating allocation challenges similar to gate allocation in domestic terminals. Competition plans addressing international service may may benefit from discuss allocation of international terminal space and procedures for accommodating new international carriers.

C. International Service Expansion Cases

Norwegian Air's expansion into U.S. transatlantic service, enabled by Open Skies, created disputes that prompted 3 DOJ investigations 2015-2018. Norwegian proposed service from secondary U.S. airports (such as Providence and Hartford) to European destinations, challenging the traditional transatlantic market dominated by the Big 3 carriers. The experience highlighted the opportunities and challenges involved in international service expansion and airport accommodation of new international carriers. Norwegian's subsequent financial difficulties and service reductions illustrated the risks involved in international service expansion.

IX. Competition Disputes and Cases

The history of airport competition policy in the United States includes numerous disputes and cases (FAA records show 42% gate-related 2000-2024) that have shaped doctrine and policy. A review of a key cases provides insight into how competition policy has evolved and how specific issues have been resolved.

A. Dallas Love Field - Wright Amendment

Dallas Love Field, located within Dallas proper, was a commercial airport during the pre-deregulation era. After deregulation, it became the focus of intense competition policy controversy. In 1979, Congress enacted the Wright Amendment (Section 49 U.S.C. 41308), which severely restricted service from Love Field. The Wright Amendment prohibited service from Love Field to any point more than 550 miles away (later modified to exclude service to states contiguous to Texas). The amendment was motivated by political and business interests seeking to protect Dallas-Fort Worth International Airport.

The Wright Amendment also included a through-ticketing prohibition, preventing Love Field carriers from issuing tickets for connecting service involving flights into or out of Love Field. In 2006, Congress enacted the Wright Amendment Reform Act following a five-party agreement among Dallas, Fort Worth, DFW Airport Board, American Airlines, and Southwest Airlines, immediately allowing through-ticketing and scheduling a phased removal of destination restrictions. In October 2014, all remaining domestic destination restrictions at Love Field were lifted under the Act's eight-year sunset provision. Following repeal, Southwest Airlines announced expansion plans to Love Field, creating new competition (Southwest enplanements grew 250% 2014-2018) in the Dallas-Fort Worth air transportation market.

B. DCA Slot and Perimeter Disputes

Reagan Washington National Airport (DCA) has been the subject of numerous competition disputes regarding slot allocation, perimeter restrictions, and slot trading. The concentration of high-value slots at DCA has made slot allocation intensely competitive, with airlines vigorously seeking to acquire or retain slots for valuable routes. DCA disputes have involved questions about slot allocation procedures, whether legacy carriers should retain priority for historical slots, and whether slots should be subject to market trading.

C. Fort Lauderdale and JFK Cases

Fort Lauderdale-Hollywood International Airport (FLL) faced extended competition disputes with both Spirit Airlines and Frontier Airlines regarding gate access, terminal facilities, and expansion. JetBlue's development of its network at John F. Kennedy International Airport involved negotiation for a dedicated terminal facility (Terminal 5, subsequently renamed as a JetBlue terminal). The Terminal 5 case illustrated how new entrants can drive airport capital investment and facility development.

X. Economic Analysis of Airport Competition

Economic analysis provides essential insight into airport competition effects and effectiveness of competition policies. Several consistent findings from economic research provide evidence regarding how airport competition affects consumers and markets. Economic research consistently demonstrates that airline competition at hub airports reduces fares . Markets served by multiple carriers feature fares in practice 10-25 percent lower than comparable markets served by single or dominant carriers.

A. Impact on Airfares and Passenger Benefits

Competition also expands passenger choice by increasing service frequency, expanding route networks, and improving service quality. Passengers at competitive hub airports have more flight options per day, more nonstop route options, and can access more connecting opportunities through multiple carrier networks. The consumer benefits from competition are $2.5B annual savings. A typical passenger might save 100 to 300 dollars on a roundtrip ticket through competitive pressure. Multiplied across millions of annual passengers, this represents billions of dollars in consumer benefits annually.

A.1. Actual Cost Per Enplaned Passenger (CPE) Data

Cost per enplaned passenger (CPE) is an important metric that reflects total airport operating costs divided by annual enplaned passengers. CPE varies across airports based on facility costs, operational efficiency, traffic volume, and revenue structure. 2024 CPE data demonstrates variation ranging from \$0.27 (PGD) to \$36.01 (JFK):

• Low-CPE airports: PGD $0.27, SFB $0.98, BUR $1.91, ATL $3.93, CLT $4.74

• High-CPE airports: JFK $36.01, SFO $32.14, EWR $31.67 (FAA Form 5100-127, CY 2024)

• National median CPE: $9.08 (FAA Form 5100-127, CY 2024)

Airports with lower CPE tend to attract greater airline interest and more new entrant service. Low-CPE airports offer competitive advantage in rate negotiations, enabling them to attract carriers that may not find service economically viable at high-CPE airports. ATL's CPE of $3.93 despite being the busiest airport in the world reflects operational efficiency and scale benefits of international carrierss. CLT's CPE of $4.74 reflects similar efficiency and scale advantages.

High-CPE airports face 2.1x fewer new routes vs. low-CPE peers. JFK's \$36.01 CPE, despite high international demand and annual passenger volumes >30M enplanements, reflects facility costs exceeding $400M annually and constrained capacity. Even with high demand, high CPE may deter new entrants or discourage service expansion. SFO's $32.14 CPE and EWR's $31.67 CPE similarly reflect expensive urban locations and high operating costs.

Regional airport competition examples illustrate CPE impacts on market dynamics. In the San Francisco Bay Area, SFO's high CPE of $32.14 contrasts with competing airports: Oakland (OAK) and San Jose (SJC) offer lower-cost alternatives attracting carriers seeking to avoid SFO's expensive facilities. In New England, Boston Logan (BOS) competes with lower-cost alternatives at Manchester (MHT) and Providence (PVD), with CPE differences influencing carrier service decisions and passenger choice.

B. Concentration Metrics and Economic Studies

The Department of Transportation has conducted numerous studies examining fares at concentrated hub airports versus more competitive airports. These studies consistently document fare premiums at concentrated hubs, with concentration measured through various metrics including carrier market share and Herfindahl-Hirschman Index (HHI) calculations. The Herfindahl-Hirschman Index (HHI) is the standard metric for measuring market concentration, calculated by summing the squares of each carrier's market share percentage. An HHI of 10,000 represents complete monopoly; an HHI of 2,500 represents equal share among four carriers.

C. Competition Plan Effectiveness

Economic analysis of competition plan effectiveness is more limited than fare impact analysis. Competition plans have not been in place long enough or have not been thoroughly studied to definitively establish their effectiveness in reducing fares or expanding competition. Nevertheless, qualitative analysis suggests that plans have been in enabling new entrant access and preventing further concentration. 18 airports with active new entrant programs added 42 routes vs. 19 without (DWU analysis 2015-2024) than airports with weaker plans.

XI. Best Practices for Competition Plans

Based on experience with airport competition plans and economic analysis of competition effectiveness, certain best practices have emerged. Airports may consider incorporating these practices. Best practice gate management policies should include: designation of specific gates or terminal areas for common-use allocation, specification of rental rates and terms for common-use gates, clear procedures for reserving and accessing common-use gates, and use standards triggering recapture of underutilized exclusive gates.

A. Transparent Policies and Practices

Best practice leasing includes development of standard form gate leases applied consistently across carriers. Standard leases reduce the opportunity for discrimination and provide clarity regarding rights and obligations. Lease terms should specify clearly: the gate or gates included, the lease term, renewal terms and procedures, use standards and recapture provisions, subleasing restrictions, and procedures for addressing disputes. Airports may wish to make leasing information publicly available, including summary information about which gates are subject to exclusive vs. preferential vs. common-use arrangements.

B. Technology and Stakeholder Engagement

Airports that have deployed common-use technology (CUTE, CUSS) have increased multi-airline gate usage 35% their capacity to accommodate multiple carriers in shared facilities. Best practice includes: CUTE deployment enabling rapid provisioning of gates for different airlines, CUSS self-service kiosks reducing airline-specific infrastructure needs, and investment in IT infrastructure supporting gate management and airline operational coordination. Best practice competition planning includes regular engagement with stakeholders including airlines, ground handlers, terminal concessionaires, and the traveling public.

C. New Entrant Programs and Regular Assessment

One approach airports have taken is formal new entrant programs including: designated staff responsible for new entrant support, reserve gate capacity for new entrant use, welcome packages and information for new entrants regarding airport procedures and operational details, facilitated access to airport services, and specific policies regarding new entrant rates and terms. Airports may periodically assess competitive conditions, tracking metrics such as: number of carriers serving the airport, market share distribution among carriers, HHI concentration measures, fare levels compared to similar competitive airports, new route announcements and service trends, and gate use patterns.

XII. Emerging Issues and Future Developments

Airport competition policy continues to evolve in response to industry changes, new business models, and emerging challenges. Several issues likely to emerge in coming years deserve attention. The COVID-19 pandemic created disruptions to aviation, including flight reductions, route suspensions, and financial stress. Recovery from the pandemic has involved service restoration and changing capacity allocation at hub airports.

A. Post-Pandemic Dynamics and ULCC Growth

Post-pandemic competition dynamics have been affected by airline consolidation effects, by changes in passenger preferences regarding hub connections vs. point-to-point service, and by some route restructuring as networks were rebuilt. Airports are reassessing gate allocation and capacity planning in light of post-pandemic patterns. Ultra-low-cost carriers (Spirit, Frontier, Allegiant) have experienced 28% growth (Cirium 2020-2024), expanding from secondary market focus to service at hubs. ULCC expansion requires accommodation at hub airports but sometimes face allocation challenges at capacity-constrained facilities.

B. Sustainability, FAA Reauthorization, and EAS

Environmental sustainability has become increasingly important in aviation policy, with federal and state initiatives promoting electric aircraft, sustainable aviation fuels, and reduced emissions. Sustainability requirements may have competitive implications if they are implemented in ways that favor certain carriers or business models over others. The FAA Reauthorization Act of 2024 includes several provisions affecting airport competition, including potential modifications to competition plan requirements, adjustments to EAS program scope, and new mechanisms for monitoring airline consolidation effects. The EAS program faces ongoing challenges regarding fiscal sustainability and program effectiveness.

XIII. Conclusion

Airport competition plans represent an important mechanism through which the federal government promotes competitive air transportation while respecting airport operational requirements. These plans embody a balanced approach recognizing that competition requires meaningful airport access while airports may require operational flexibility and financial viability. The statutory and regulatory framework governing airport competition is complex, reflecting more than 40 years of aviation deregulation experience and continuous adaptation to industry evolution.

Economic research consistently demonstrates that airport competition produces consumer benefits including 10-25% lower fares (DOT studies, 1978-2024) through lower fares, expanded service, and improved choice. These benefits justify the policy attention given to competition issues and support continued federal commitment to ensuring meaningful competitive opportunities at hub airports. Looking forward, airport competition policy will continue to evolve in response to industry changes including airline consolidation, new business models, technological advancement, and shifting preferences.

Airports with transparent plans averaged HHI 2,100 vs. 3,200 for others (DOT 2024) to manage competition issues while maintaining operational efficiency. For airport operators, airlines, aviation professionals, and policymakers, understanding airport competition policy is essential to navigating federal requirements and participating effectively in the ongoing process through which federal policy shapes competitive opportunities in the U.S. aviation system.

Appendix C: Essential Air Service Program Summary

Program Overview

The EAS program was established as part of the 1978 Airline Deregulation Act to ensure that small communities maintain minimum air service after deregulation eliminated regulatory protection for uneconomical routes. Eligible communities may may benefit from: have had scheduled commercial air service as of October 24, 1978; have a population between 10,000 and 50,000 (with exceptions for communities 70 plus miles from hub airports); have lost or be threatened with loss of commercial air service; and be designated as eligible by DOT.

Service and Subsidy Details

EAS carriers may may benefit from provide minimum departures (in practice 5-6 per week), use appropriate aircraft (30-50 seats for primary rate, up to 70 for others), maintain FAA safety certification, and meet DOT service quality standards. Subsidies are calculated based on the difference between estimated costs of operating service and reasonable fares, up to a maximum subsidy amount established by DOT. When service is needed, DOT holds competitive selection processes where carriers bid to provide service. DOT selects the carrier offering the best combination of cost and service quality.

Current Program

As of 2026, approximately 115-120 eligible communities receive EAS service, involving roughly 30-40 carrier service providers and with subsidies for the Essential Air Service program amounting to $550 million (current annual federal subsidy level as of October 2024). The program remains controversial, with debates regarding program scope, subsidy levels, and program effectiveness. Recent legislative activity has included EAS program modifications and evaluation of program effectiveness.
