Cargo Airline Economics and Airport Impact

Cargo Airline Economics and Airport Impact

Last updated: March 29, 2026

Cargo airlines generate airport revenue through mechanisms distinct from passenger carriers—primarily landing fees calculated on Maximum Gross Landing Weight (MGLW) and cargo facility leases rather than terminal rents and concession percentages. For airport CFOs and bond analysts at facilities where cargo accounts for over 50% of total airport Maximum Gross Landing Weight (per FAA CY2024 all-cargo landed weight rankings), the revenue stability, volatility, and capital requirements of cargo operations differ structurally: at MEM, FedEx accounts for 99% of cargo handled, whereas at large-hub passenger airports cargo comprises a median of 7% of non-passenger revenue (DWU analysis of ACFRs and FAA all-cargo rankings, FY2024). This analysis examines the business models of the four largest U.S.-related cargo operators, landing fee structures for freighters versus passenger aircraft, facility lease economics, the belly-versus-freighter trade-off, concentration risk, forward fleet orders and aircraft retirements, de minimis elimination impacts, and strategic challenges facing cargo-dependent airports including Memphis International (MEM), Louisville Muhammad Ali International (SDF), Chicago O'Hare International (ORD), and Daniel K. Inouye International (HNL).

Four Cargo Business Models Generate Distinct Airport Revenue Streams

The U.S. cargo sector is structured around four distinct operator types, each producing different revenue patterns for host airports:

FedEx Memphis Hub

FedEx operates the world's largest cargo airline and concentrates its U.S. domestic sorting operation at Memphis World Hub: 940 acres with 171 aircraft gates, 84 miles of conveyor belt, and 484,000 package processing capacity per hour. FedEx accounts for 99% of all cargo handled at MEM in FY 2024. The Memphis-Shelby County Airport Authority reported cargo operating revenues of $47.7 million in FY 2024, comprised of $36.3 million in cargo landing fees, $8.9 million in ground rents, and $2.4 million in other rentals (MEM ACFR FY2024).

Fleet Modernization and USPS Impact: In Q4 FY2025, FedEx retired 7 A300-600s, 3 MD-11s, and 2 757-200s (FreightWaves), resulting in a $21 million impairment. Over three fiscal years (FY2022–FY2025), FedEx achieved a net reduction of 31 mainline jets—a 7% fleet reduction. In March 2025, FedEx ordered 8 additional 777F freighters (3 deliveries in 2026, 5 in 2027) and 2 used 777Fs (NDTA), bringing total 777F capacity to 57 aircraft. MD-11 retirement, originally scheduled for 2028, has been extended through 2032 to manage capital expenditure within a capped budget of approximately $1 billion annually.

Memphis Hub Expansion: FedEx Secondary 25, a 1.3-million-square-foot automated small package sort facility, opened in October 2024 and handles 56,000 packages per hour, complementing the primary 940-acre hub. A third facility, Secondary 26, is under construction and scheduled for 2027 completion. These expansions reflect FedEx's DRIVE program, which achieved $2.2 billion in cumulative cost savings through FY2025 versus FY2023 baseline and is targeting an additional $1 billion in FY2026 (FreightWaves).

USPS Contract Expiration: FedEx's USPS contract expired on September 29, 2024, creating a $500 million revenue headwind in FY2025 (Supply Chain Dive) (FedEx 10-K). The Memphis-Shelby County Airport Authority's FY2024 ACFR explicitly warned that FY2025 cargo activity was expected to decline below FY2024 levels due to the USPS contract expiration (MEM ACFR FY2024). CY2024 cargo throughput fell 3.3% from CY2023 to 3.754 million metric tons, while global cargo grew 8.4% (MEM ACFR FY2024). This divergence reflects FedEx's operational adjustments following USPS contract expiration.

Freight Spinoff: On December 19, 2024, FedEx announced plans to separate its Freight and Express divisions. The Form 10 was filed January 15, 2026, with separation targeted for June 1, 2026, and the new Freight company to trade as FDXF on NYSE. According to FedEx.s Form 10, Memphis air operations will remain with the Express unit following the Freight spinoff.

Landing Fee Escalation: MEM landing fees increased from $1.5509 per 1,000 lbs in FY2024 to $2.2976 in FY2025 (+48%) and $2.6700 in FY2026 (MEM rate schedule). Terminal facility rent increased correspondingly from $81.87 to $114.63 to $129.83 per square foot.

UPS Worldport at Louisville

UPS Worldport at SDF spans the equivalent of 90 football fields (5.2 million square feet), processes approximately 2 million packages per day with capacity for 420,000 packages per hour, and accommodates 125 aircraft and approximately 360 daily flights. SDF ranked 3rd in North America for cargo operations in 2024, handling 6.95 billion pounds (3.15 million metric tons), a 16% increase over 2023 (Louisville ACFR). By CY 2024, SDF recorded approximately 17.985 billion pounds of all-cargo landed weight, ranking 4th nationally after MEM (21.215B lbs).

Network Restructuring and Amazon Reduction: UPS handled an average of 22.4 million packages per day in FY2024 globally. In January 2025, UPS agreed to reduce Amazon volume by more than 50% by the end of H2 2026, reflecting the company's strategic shift away from low-margin volume. UPS fully insourced SurePost operations effective January 1, 2025, following expiration of the USPS NSA on December 31, 2024, and implemented SurePost rate increases of +9.9%.

Efficiency Reimagined Program: UPS's Efficiency Reimagined initiative represents the largest network reconfiguration in company history, targeting approximately $1 billion in annual cost savings. In January 2026, UPS announced an additional 30,000 job cuts, with 24 facility closures planned for H1 2026, following 48,000 cuts in 2025 and 14,000 in 2024. Full-year 2025 revenue declined $2.4 billion versus 2024. No closures of Worldport or major sort hubs have been announced—UPS describes Worldport as a central node in its network architecture (UPS 10-K FY 2024).

Amazon Air at Cincinnati

Amazon constructed its principal hub at Cincinnati/Northern Kentucky International (CVG) on a $1.5 billion investment: a 600-acre campus with an 800,000-square-foot sortation building, capacity for over 100 aircraft and 200 daily flights (Amazon investor relations). Amazon does not operate aircraft; it contracts with carriers such as Air Transport Services Group (ATSG) and Sun Country Airlines for pilots, maintenance, and flight operations.

Fleet Composition by Operator: Amazon's contracted fleet comprises multiple carriers with distinct aircraft types and expansion plans. Sun Country Airlines expanded from 20 to 22 Boeing 737-800 Converted Freighter (737-800BCF) by July 2026, with a contract extension through 2030 and options extending to 2037; Sun Country's 2025 cargo revenue reached $155 million, a 44.6% increase year-over-year (FreightWaves). ATSG operates multiple Boeing 767-300F units and is converting 29 Airbus A330-300 passenger aircraft to freighter (P2F) configuration, with the first 4 deliveries completed in 2025 (Statista). A Hawaiian Airlines/Alaska Airlines subsidiary operates 10 new Airbus A330-300F widebody freighters under a new contract, providing a 17% increase in capacity compared to the narrowbody fleet (FreightWaves). ASL Airlines (Europe) operates approximately 12 Boeing 737-800F units for Amazon's international operations.

Network Expansion and Capacity Metrics: Amazon's fleet metrics show a 14% rise in tonnage capacity year-over-year; over 75% of domestic ton-miles are now operated on widebody aircraft, reducing short-haul operations under 400 miles to 5.1% of total tonnage; and 39% of Amazon Air flights operate nocturnally (DePaul Chaddick Institute).

CVG Hub Capacity and Utilization: CVG's 600-acre campus operates at approximately 58 flights per day as of November 2024, against a design capacity of 200 daily flights, reflecting Amazon's shift toward regional fulfillment and reduced short-haul reliance on air. Sun Country opened a new CVG operations and maintenance hub in February 2026, expanding infrastructure for aircraft maintenance and crew scheduling.

Third-Party Cargo Initiative: In September 2024, Amazon launched third-party cargo services (FreightWaves), competing directly with FedEx and UPS for containerized freight and balancing empty return legs on regional routes. This initiative addresses the regional fulfillment strategy's byproduct: northbound empty aircraft capacity on return flights from regional distribution hubs.

Five-Hub Network: Amazon Air operates from five primary hubs — Cincinnati (CVG), Fort Worth Alliance (AFW), San Bernardino (SBD), Lakeland (LAL), and a fifth hub location, allowing geographic distribution of sorting capacity and regional route optimization.

Atlas Air ACMI Model

Atlas Air operates under the Aircraft, Crew, Maintenance, and Insurance (ACMI) model: the lessor provides aircraft and flight operations; the customer bears load factor, yield, and route risk. Atlas operated 14% of global widebody freighter capacity in 2024, flew 51,859 flights, and added 8 widebody freighters to reach a fleet of 121 aircraft. An Apollo-led investment group acquired Atlas in March 2023, delisting it from Nasdaq. The ACMI model generates minimal direct airport revenue; landing fees and facility charges accrue to the customer airline's account, not the lessor's.

Landing Fee Structures Reflect Cost Center Allocation—Not Universal Cargo Discounts

Landing fees at U.S. airports are assessed per 1,000 pounds of MGLW, but the rate applied to cargo carriers depends on the airport's cost structure methodology. Cargo carriers do not use passenger terminals, concourses, or baggage systems; for example, at LAX, FedEx and UPS lease dedicated cargo facilities and do not lease terminal space. Of 31 large-hub airports, 12 (39%) use compensatory or hybrid cost structures that separate cargo airfield costs from passenger terminal costs, charging cargo carriers only for the airfield and cargo-related infrastructure they use.

The following table compares published landing fee rates at selected major cargo and large-hub airports:
