United Blocks American’s Gate Expansion at Chicago O’Hare Airport

United Airlines is intensifying its efforts against American Airlines to maintain dominance at Chicago’s O’Hare International Airport (ORD). CEO Scott Kirby emphasized the airline’s commitment to not allow American to secure additional gates at the airport in 2026.

O’Hare Airport Gate Allocation and Current Operations

In October 2025, American Airlines lost five gates at O’Hare, leaving it with a total of 59 gates, while United operates 95 gates. The Chicago Department of Aviation allocates gates based on the average number of daily departures from the previous year. In 2025, United had 541 daily departures, compared to American’s 412.

Upcoming Changes and Strategic Moves

American Airlines plans to increase its operations to over 500 departures per day in 2026. However, United anticipates that American will regain three of its lost gates this year after adding new flights in 2025. This situation underscores a continuing turf battle between the two carriers.

Competitive Strategies and Market Analysis

• United has initiated new routes to compete directly with American, including destinations like Erie International Airport (ERI), Lincoln Airport (LNK), and Tri-Cities Airport (TRI).
• The rivalry dates back to the 1980s when American built its hub at ORD, intensifying again after Kirby’s transition to United in 2016.

United’s aggressive strategy has resulted in American reportedly losing approximately $500 million at ORD in 2025, while United earned close to $500 million in profit. Kirby stated that losses for American could reach $1 billion in Chicago.

Response from American Airlines

An American spokesperson countered Kirby’s claims by highlighting the benefits of competition at O’Hare. They argued that multiple hub carriers provide consumers with better fares and more travel options, contributing positively to the local economy.

Future Developments and Industry Perspectives

Analysts suggest that American is unlikely to withdraw from the competitive landscape at ORD. The airline’s loyalty program and other hubs can absorb potential losses at O’Hare.

• Jamie Baker, a JP Morgan analyst, indicated that American’s commitment to Chicago is evident through strategic growth and investment.
• Kirby believes that airlines should avoid maintaining loss-making routes and hubs to ensure long-term success.

This competition highlights a pivotal moment for both airlines at a critical hub, as they navigate operational adjustments and strategic expansions.
