Introduction

Regional airlines operate under a fundamentally different business model than mainline carriers, flying on behalf of major airlines through capacity purchase agreements (CPAs). Unlike low-cost carriers that control their own route networks and revenue pricing, regional carriers fly routes, aircraft, and crew for mainline partners (American, United, Delta, Southwest), who control revenue and pricing. This dynamic creates a unique economics profile that has been reshaped in 2024-2026 by pilot supply tightness, consolidation among regional operators, and evolving CPA terms negotiated by increasingly powerful regional carriers.

This profile provides an overview of the regional airline sector, examining the economics of the capacity purchase model, the major players (SkyWest, Republic Airways post-Mesa merger, Envoy, PSA, Piedmont, GoJet), pilot pipeline crisis dynamics, and the structural changes underway in the regional aviation market.

The Capacity Purchase Agreement Model: How Regional Airlines Work

Capacity purchase agreements are the foundational business model for regional airlines. Under a CPA, a regional airline (e.g., SkyWest) operates flights on behalf of a mainline carrier (e.g., United) under the mainline's brand and flight numbers.

Agreement Structure: A typical CPA specifies:

• Capacity Commitment: The regional agrees to operate a specified number of seats per month (e.g., 50,000 available seat miles per month)
• Revenue Guarantee: The mainline guarantees a minimum monthly payment to the regional regardless of load factor or revenue realization. This reduces regional airlines' exposure to demand volatility.
• Pricing and Yield Management: The mainline sets fares, manages yield, and captures excess revenue (if actual revenue exceeds the guarantee). The regional is "insulated" from pricing and demand volatility—it receives the guarantee payment in full.
• Operational Standards: The CPA specifies on-time performance, safety standards, and service quality requirements, typically tied to metrics and penalties for non-compliance
• Aircraft and Crew Specification: The CPA often specifies aircraft type (e.g., Embraer E175 aircraft), crew uniforms, and service standards to maintain brand consistency

Regional Airline Economics: Regional airlines earn revenue by delivering promised capacity to the mainline partner at contractually specified cost structure. Profitability depends on:

• Controlling operating costs (labor, fuel, maintenance) below the CPA revenue guarantee
• Operating at high aircraft utilization to spread fixed costs across more flights
• Achieving operational excellence (on-time, safety) to avoid CPA penalties
• Negotiating favorable CPA terms when renewing or renegotiating agreements

Key Risk Factor: CPA Renegotiation: When CPAs expire, regional carriers face renegotiation with mainline partners who have significant bargaining leverage. A mainline partner can threaten to deploy larger aircraft (reducing regional carrier capacity), shift routes to other regional partners, or internalize routes by using mainline aircraft. This asymmetric bargaining power has historically compressed regional carrier margins and limited profitability growth.

SkyWest Inc.: The Dominant Regional Carrier

SkyWest Inc. is the largest regional airline in North America, operating approximately 500 aircraft serving United, Delta, and American Airlines through multiple carrier brands (SkyWest Airlines, SkyWest Express).

2024 Financial Results: SkyWest reported strong financial performance in 2024:

• Q4 2024: Net income of $97 million ($2.34 per diluted share), up from $18 million ($0.42 per share) in Q4 2023
• Full Year 2024: Net income of $323 million ($7.77 per diluted share), up from $34 million ($0.77 per share) in 2023
• Operating Expenses: Q4 2024 operating expenses of $800 million (up 10% from $724 million in Q4 2023), driven by increased flight production

The significant year-over-year improvement reflects the impact of new, higher-value CPA agreements with mainline partners and operational excellence. SkyWest's ability to negotiate better CPA economics with United, Delta, and American is a key strategic advantage as regional carriers gain bargaining power due to pilot supply tightness.

Fleet and Growth: SkyWest operates approximately 500 aircraft, with a mix of Embraer E175 narrow-bodies and Bombardier CRJ aircraft. The company has committed to operating 278 E175 aircraft by end of 2026, signaling significant growth and modernization. The E175 is the industry standard for 70-80 seat regional aircraft, offering fuel efficiency and customer comfort advantages over older CRJ aircraft.

Operational Scale: SkyWest's 500-aircraft operation spans over 240 destinations across North America, making it the backbone of United, Delta, and American's regional route networks. This scale provides significant leverage in CPA negotiations and allows cost absorption across multiple mainline partners.

Republic Airways and Mesa Air Group: Post-Merger Consolidation

Republic Airways and Mesa Air Group completed a merger on November 25, 2025, creating the second-largest regional airline in North America by fleet size.

Combined Entity Scale: The post-merger Republic Airways operates approximately 310 regional jets, servicing roughly 1,300 daily departures to over 80 destinations across the U.S. and Canada. Prior to the merger, Republic Airways operated 900 daily flights independently.

Republic Airways Pre-Merger Financial Performance: Republic Airways achieved peak revenue of approximately $1.3 billion in 2024, making it a substantial regional operator competing directly with SkyWest for CPA agreements with major airlines.

Strategic Rationale: The Republic-Mesa merger consolidates two struggling regional carriers with overlapping CPA agreements and aircraft fleets. The combined entity is expected to achieve cost synergies through:

• Fleet standardization and maintenance consolidation
• Overhead reduction and elimination of duplicate corporate functions
• Improved bargaining leverage with mainline partners during CPA renegotiations
• Access to better capital markets financing for aircraft acquisition and modernization

Post-Merger Outlook: The merged Republic Airways is positioned to compete more effectively with SkyWest, potentially capturing additional CPA opportunities and supporting more favorable agreement economics. However, the combined entity remains substantially smaller than SkyWest's 500-aircraft operation, maintaining a hierarchical competitive structure.

Envoy Air, PSA Airlines, Piedmont, and GoJet: The Second Tier

Beyond SkyWest and Republic Airways, several smaller regional carriers operate significant fleets:

Envoy Air (American Eagle): Envoy operates approximately 200-250 aircraft for American Airlines under the American Eagle brand. Envoy is wholly owned by American Airlines, providing operational control but limiting independent growth optionality. Envoy's financial performance is consolidated into American's results.

PSA Airlines (American Eagle): PSA operates approximately 100-150 aircraft for American Airlines under the PSA/American Eagle brand. Like Envoy, PSA is owned by American and operates under American's CPA and operational control.

Piedmont Airlines: Piedmont operates approximately 50-100 aircraft for American Airlines under the Piedmont brand, serving secondary and tertiary American Eagle markets.

GoJet Airlines (United Express): GoJet operates approximately 100-150 aircraft for United Airlines under the United Express brand. GoJet is privately held and competes for United's regional capacity allocation alongside SkyWest.

Collective Market Position: Envoy, PSA, Piedmont, and GoJet, in aggregate, operate substantial fleets comparable to or exceeding Republic Airways' fleet size. However, these carriers are constrained by single-mainline relationships (Envoy/PSA/Piedmont with American; GoJet with United), limiting negotiating leverage and strategic optionality compared to SkyWest's diversified mainline partnerships.

The Pilot Pipeline Crisis: Capacity Constraint and CPA Dynamics

A structural change is reshaping regional airline economics: pilot supply has tightened significantly, particularly for first officers (captain candidates). This phenomenon is driven by several factors:

1. Post-COVID Pilot Retirements: The COVID-19 pandemic accelerated early retirements of senior pilots at major airlines. Historically, retired regional airline pilots would move to majors, creating "slots" for regional pilots to advance. Post-COVID, this pipeline has been disrupted, with major airlines retaining pilots through retirement windows and reducing hiring pace.

2. ATP Requirements and Training Costs: FAA regulations require 1,500 flight hours prior to first officer certification—a significant training cost and time barrier for aspiring pilots. The cost of flight training (approximately $200K-300K) deters many candidates, constraining the pilot supply pipeline.

3. Career Trajectory Economics: Regional pilots earn $40K-70K annually as first officers, significantly below mainline first officer compensation ($150K+). Many potential pilots view regional captain positions ($120K-170K) as insufficiently rewarding given the career duration required (5-10 years as regional first officer before captain upgrade). Some trained pilots instead pursue alternative careers (corporate aviation, military, other industries).

4. Scope Clause Constraints: Mainline airlines' labor contracts include "scope clauses" limiting the size of regional aircraft (typically 70-80 seats) and the percentage of mainline capacity that can be outsourced to regional partners. These clauses protect mainline pilot jobs but create artificial constraints on regional airline growth and limit the pipeline of regional pilots advancing to mainline positions.

Impact on Regional Carriers: Pilot supply tightness is shifting bargaining leverage to regional carriers for the first time in industry history. Regional carriers can credibly threaten inability to deliver capacity unless they receive improved CPA economics that allow higher pilot wages. SkyWest's strong 2024 financial results reflect improved CPA terms secured by leveraging pilot supply constraints.

CPA Negotiation Dynamics (2024-2025): Regional carriers negotiating new or renewed CPAs are achieving improved economics by highlighting pilot supply constraints and threatening capacity reductions if CPA economics do not improve. Major airlines, facing pressure to maintain capacity growth and fearing service disruptions, are accepting higher CPA payments to secure regional carrier capacity commitments.

Cost Structure: Labor, Fuel, and Utilization

Regional airline cost structures are heavily dependent on labor, fuel, and aircraft utilization:

Labor Costs (40-50% of total operating costs): Pilots and flight attendants represent the largest regional operating cost. Pilot compensation for first officers ranges from $40K-80K annually depending on seniority and airline. Captain compensation ranges from $120K-180K. Flight attendants earn $35K-60K. Labor costs have been escalating significantly (5-10% annually) due to pilot supply tightness and market wage pressure.

Fuel Costs (20-30% of total operating costs): Fuel costs at $2.40-2.50 per gallon in 2024 represent a significant operating expense. Regional airlines operate modern, fuel-efficient aircraft (E175, CRJ-series) but lack the scale for aggressive fuel hedging strategies available to major airlines.

Aircraft Operating Costs (15-20%): Lease payments, maintenance, insurance, and other aircraft-related costs. Most regional aircraft are leased rather than owned, with lease payments locked in contractually and escalating based on market conditions.

Utilization as Margin Driver: Regional carriers maximize margin by achieving high aircraft utilization (12-14 flight hours per day is typical for regional operations). Higher utilization spreads fixed costs across more flight hours and reduces per-seat costs. Regional carriers optimize crew scheduling and turn-around procedures to maximize utilization within safety and regulatory constraints.

Outlook: Consolidation, CPA Renegotiation, and Pilot Economics

Consolidation Trend: The Republic-Mesa merger is likely the first of additional regional airline consolidation. Smaller operators (GoJet, Piedmont) may be acquired by larger carriers or consolidated to reduce overlapping regional fleets. Consolidation is expected to continue through 2026-2027, resulting in a three-carrier market: SkyWest, combined Republic Airways, and smaller independent operators.

CPA Economics Improvement: Pilot supply tightness will likely persist through 2025-2026, allowing regional carriers to achieve improved CPA economics. Major airlines will accept higher CPA payments to secure capacity and ensure service reliability, recognizing pilot supply as a critical constraint on growth.

Fleet Modernization: Regional carriers are accelerating fleet retirement of older aircraft (CRJ-200, CRJ-700) and deploying modern E175 aircraft. Fleet modernization improves fuel efficiency, reduces maintenance costs, and supports higher revenue per seat through improved customer experience and longer-range capability.

Pilot Compensation Escalation: Regional pilot compensation will continue rising, driven by tight supply and mainline demand for experienced pilots. First officer compensation could reach $80K-120K by 2027, and captain compensation could exceed $180K-200K, pressuring regional carrier profitability unless offset by improved CPA economics.

Risk Factors and Industry Challenges

Economic Downturn and Demand Destruction: A recession would reduce regional demand and allow major airlines to reduce CPA commitments, reversing recent regional carrier gains in negotiating leverage.

Mainline Insourcing: Major airlines could reduce reliance on regional partners by deploying larger narrow-body aircraft on routes currently served by regional partners, eliminating regional capacity and forcing consolidation.

Labor Cost Escalation Outpacing CPA Growth: If pilot and labor costs escalate faster than CPA economics improve, regional carrier margins could compress despite improving negotiating power.

Fuel Price Volatility: A return to $3.00+ per gallon would significantly impact regional airline profitability, as CPAs typically include fuel price escalation formulas that lag market price movements.

Conclusion

Regional airlines are experiencing a structural shift in bargaining dynamics, driven by pilot supply tightness that is raising regional carrier leverage in CPA negotiations with major airlines. SkyWest's strong 2024 results and the Republic-Mesa merger consolidation signal a more robust regional airline sector. However, the regional model remains dependent on major airline relationships and capacity purchase agreements, limiting fundamental independence. The next 2-3 years will test whether regional carriers can sustain improved economics despite inevitable labor cost escalation and whether consolidation can create sufficient scale and operational efficiency to support profitable independent growth.
