American Airlines Returns to Court to Halt O’Hare Gate Shuffle

Key Takeaways

• American Airlines sues City of Chicago to block gate reallocation at O’Hare starting October 1, 2025.
• United Airlines would gain seven gates, increasing from 88 to 95, while American’s gates drop from 71 to 59.
• Court decision will affect competition, flight options, and future airport gate agreements across the US.

A major legal fight is unfolding at Chicago O’Hare International Airport, one of the world’s busiest travel hubs. American Airlines is taking the City of Chicago and United Airlines to court, aiming to stop a planned gate reallocation set for October 1, 2025. This dispute is about much more than just airport gates—it could change how airlines compete, how travelers move through O’Hare, and even how future airport agreements are handled across the United States 🇺🇸.

Let’s break down what’s happening, why it matters, and what it means for airlines, passengers, and the future of O’Hare.

What’s Happening at O’Hare?

On July 8, 2025, court documents revealed that American Airlines is asking a federal judge to block the City of Chicago from moving forward with a new gate assignment plan at O’Hare. The airline wants a preliminary injunction—a court order that would stop the city’s plan until at least April 1, 2027. American argues that the city’s actions break a 2018 agreement called the Airline Use and Lease Agreement (AULA), which sets the rules for how gates are shared and assigned at the airport.

The new gate plan is scheduled to start on October 1, 2025. If it goes ahead, United Airlines will get seven more gates, bringing its total to 95, while American’s share will drop from 71 to 59 gates. American says this change will hurt its business, reduce competition, and force it to rethink how it operates at O’Hare.

Why Is This Gate Reallocation So Important?

Airport gates are where planes park to load and unload passengers. At a big airport like O’Hare, the number of gates an airline controls can decide how many flights it can offer, how smoothly it can run its schedule, and how much it can grow. Losing gates can mean fewer flights, less flexibility, and a weaker position against competitors.

American Airlines claims that if the gate reallocation happens now, it will suffer “irreparable harm.” The airline says it will have to cut flights, change its business plans, and might lose its strong position at O’Hare. American is especially worried because it’s running its biggest summer schedule ever at O’Hare in 2025, with 25% more seats and 18 new destinations.

On the other hand, United Airlines argues that the new gate plan is fair. United says it’s running more flights than its current gate share allows and that the new plan simply matches gates to actual usage. United’s president, Brett Hart, has even accused American of “neglecting Chicago” and trying to block progress through lawsuits instead of investing in the airport.

Background: The 2018 Airline Use and Lease Agreement (AULA)

The heart of the legal fight is the 2018 Airline Use and Lease Agreement (AULA). This agreement sets the rules for how O’Hare’s gates are assigned and when those assignments can be changed. According to American Airlines, the AULA says no new gate reallocation should happen until at least April 2027. This delay is supposed to give time for terminal construction projects to finish and for airlines to adjust during a period called the “Gate Space Ramp-up Period.”

The City of Chicago disagrees. City officials say all the conditions for a new gate plan have been met, including finishing the Terminal 5 extension and moving airlines to their new spots. The city believes it’s following the agreement and that the new gate plan is legal and fair.

Who Are the Main Players?

• American Airlines: Wants to keep its current gates until at least 2027. Argues that the city is breaking the AULA and that losing gates now would hurt its business and reduce competition at O’Hare.
• United Airlines: Supports the city’s plan. Says the new gate assignments reflect actual flight numbers and growth. United is adding more flights, hiring more staff, and wants more gates to match its expansion.
• City of Chicago/Chicago Department of Aviation (CDA): Believes it’s following the rules set out in the AULA. The city says the new gate plan is fair and needed to keep up with changes at the airport. Officials have not commented further because of the ongoing lawsuit.

How Did We Get Here? Key Dates and Events

• May 2025: American Airlines files a lawsuit against the City of Chicago, challenging the planned gate reallocation.
• June 2025: The city awards five more gates to United Airlines, setting the stage for the new plan.
• July 2025: American asks the court for a preliminary injunction to stop the gate changes. Court documents become public.
• October 1, 2025: The new gate plan is set to take effect, unless the court blocks it.

What’s at Stake for Each Group?

American Airlines:
– Faces a drop from 71 to 59 gates if the new plan goes ahead.
– May have to cut flights, change schedules, and rethink its growth at O’Hare.
– Worries about losing its strong position at the airport, especially after investing in new routes and more seats for 2025.

United Airlines:
– Would jump from 88 to 95 gates, giving it more room to grow.
– Already runs more than half of O’Hare’s departures, and the extra gates would help it add even more flights.
– Sees the new plan as a reward for its investment and growth in Chicago.

Passengers:
– Could see changes in flight options, schedules, and prices.
– More gates for United might mean more flights and destinations, but less competition could also affect fares and service.
– If American has to cut back, travelers loyal to American may have fewer choices at O’Hare.

Other Airlines:
– The outcome could set a precedent for how gate disputes are handled at O’Hare and other major airports.
– Smaller airlines may watch closely to see if big carriers can use legal agreements to protect their turf or if cities can change gate assignments to match growth.

Legal and Policy Implications

The court’s decision will have a big impact on how airports and airlines work together in the future. If the judge sides with American Airlines and grants the injunction, the current gate assignments will stay in place until at least 2027. This would limit United’s growth and protect American’s position at O’Hare.

If the city wins, United will get more gates, and the balance of power at O’Hare could shift. The case will also show how much power cities have to change airport operations, even when long-term agreements are in place.

Aviation experts say this fight is part of a bigger trend. Major airlines are trying to lock in their positions at key airports, while cities want to make sure gates are used efficiently and reflect real growth. As reported by VisaVerge.com, these kinds of disputes are becoming more common as airlines compete for space and passengers at the busiest airports.

Industry Analysis: What Are the Experts Saying?

Aviation analysts point out that the O’Hare dispute highlights a growing struggle at big airports. Airlines want to protect their “fortress hubs”—airports where they have a big presence and lots of loyal customers. At the same time, cities and airport authorities want to make sure gates are used by the airlines that need them most.

Some experts say that strict lease agreements like the AULA can help keep things fair, but they can also make it hard for airports to adapt to changes. Others argue that cities need the power to adjust gate assignments as airlines grow or shrink, so that travelers get the best service and most choices.

The O’Hare case is being watched closely by other airports and airlines across the United States 🇺🇸. The outcome could influence how future lease agreements are written and how disputes are settled.

What Happens Next?

The federal court is expected to make a decision on American’s request for a preliminary injunction in the coming weeks. If the court blocks the gate reallocation, the current assignments will stay in place until at least 2027. If not, the new plan will start on October 1, 2025.

Both American and United are investing in O’Hare’s ongoing modernization, including new terminals and better passenger facilities. But the outcome of this legal fight will shape how the airport grows and which airlines have the most power for years to come.

Negotiations between the city and the airlines could still happen, but for now, the courtroom is the main battleground.

How Does This Affect Immigration and International Travel?

O’Hare is a major entry point for international travelers coming to the United States 🇺🇸. Changes in gate assignments can affect how quickly passengers move through customs, how many international flights are available, and even which airlines offer the best connections.

For immigrants, students, and business travelers, fewer flights or less competition could mean higher prices or fewer choices. On the other hand, if United adds more international routes, travelers might see new destinations and better connections.
