A major dispute has flared up at one of the busiest airports in the United States 🇺🇸, O’Hare International Airport, as American Airlines has taken legal action against the city of Chicago. At the center of the conflict is the airport’s decision to favor one carrier—United Airlines—with additional gates, while reducing the space available to American Airlines. The outcome of this case carries wide-ranging effects for air travelers, airlines, airport management, and the city itself.
O’Hare’s Gate Battle: What’s Happening?
On May 2, 2025, American Airlines filed a lawsuit in federal court in Illinois. The airline’s main complaint is that Chicago is reallocating gates at O’Hare International Airport in a way that is not fair. The city’s current plan, if it goes forward, will give United Airlines six extra gates. At the same time, American Airlines will lose four gates—reducing its ability to operate flights, serve passengers, and compete with United Airlines at O’Hare.
As reported by VisaVerge.com, this issue is about much more than gates. Gates are the access points where planes park, unload, load passengers, and prepare for their next trip. Losing gates means fewer spots to serve flights and fewer chances to increase schedules. For large airlines like American and United, access to gates at a crucial airport like O’Hare rules their ability to compete, grow, and provide options to travelers.
Currently, United Airlines operates about 40% of O’Hare’s gates but claims it handles more than half of all flight departures from the airport—about 52% last year. In contrast, American Airlines says it occupies 41% of the gates but accounts for only 37% of departures. This means that with more gates in United’s control, they could run even more flights, get ahead in offering services, and possibly push out rivals.
Why Is American Airlines Suing Chicago?
American Airlines says the city broke the rules. The basis for the lawsuit comes from the 2018 Airline Use and Lease Agreement, commonly referred to as the AULA. The AULA sets out when and how the city can re-shuffle gate assignments among the airlines that use O’Hare International Airport.
Here are the main legal points American Airlines makes in its complaint:
- The gate shuffle was started too early. American says that changes cannot begin before certain construction projects are complete. In particular, all the “L-Stinger gates”—a new part of Terminal 3—had to be up and running before any gates could be taken away or moved. American claims these gates did not open until March 2025.
- American believes the AULA says any reallocation should allow airlines the chance to earn a “fair share” of gates. According to American Airlines, it was denied that chance under the current plan.
- The airline argues that the changes should not even be considered until 2027, when the agreement allows for gate numbers to be discussed again.
American Airlines accuses the city of making a secret deal with United Airlines. In statements filed with the court, American says it was “deceived and betrayed” by what it believes was a backroom agreement that ignored the rules everyone agreed to in 2018. The company wants the court to stop the city from any changes until at least 2027 so that it can keep up with competition at O’Hare.
United Airlines’ Response
United Airlines has fired back strongly. In a message sent to its employees on May 12, 2025, United called American’s lawsuit a “last-ditch effort” to block the plan. United insists that the reallocation process has been going on for more than a year and a half—it says it reached a deal with the city for more gates about 18 months ago.
United Airlines highlights how it is already the leader at O’Hare International Airport. This summer, for example, United has about 100 more daily flights from O’Hare than American Airlines. Andrew Nocella, United’s Chief Commercial Officer, says the new gates support their “United Next plan”—a business plan designed to make United the top choice for travelers leaving from key airports like O’Hare.
United Airlines also points to the numbers: it claims that although it handles over half of the airport’s departures, until now it has had less than half the gates. The airline argues it only wants a fair share rather than an unfair advantage and that it has grown its schedule to meet demand in Chicago.
The Stakes: Who Benefits and Who Loses?
This drama at O’Hare International Airport is not just about two airlines arguing over airport real estate. It’s about competition, ticket prices, choices for passengers, and the power airlines have at one of the world’s largest travel hubs.
United Airlines is based in Chicago and has been the dominant player at O’Hare for years. Its leaders have said openly that it needs to be the number one carrier in big cities like Chicago if it wants to be seen as a global, premium airline. Company bosses have also suggested that, by pushing American Airlines aside, United could be the only hub carrier running the city’s biggest airport in the future.
American Airlines, on the other hand, argues that if United grabs an even bigger slice of the airport, the results will be bad for travelers. American’s legal team points to a basic idea in economics: when one company has too much control, prices usually go up and choices go down. By keeping a strong presence at O’Hare, American says it can help protect lower fares and make sure passengers have alternatives.
Despite this large battle in the background, passengers flying out of O’Hare International Airport have actually seen domestic ticket prices drop this summer. The average fare has gone down by 3%, to $386. That means, for now, competition still seems healthy. But, if one airline were to dominate, this could change.
A Legal Tangle with National Effects
What happens at O’Hare International Airport will not stay at O’Hare. The result of American’s lawsuit and the city’s decision could shape how other airports around the United States 🇺🇸 manage the tough questions of who gets access and under what conditions.
If the courts agree with American Airlines, large airports could have less flexibility to adjust gates based on changes in flight schedules, demand, or future growth. This could lock in the current distribution of gates for years at a time, possibly stopping airports from reacting quickly to new business opportunities or big shifts in airline strategy.
If, instead, the court sides with Chicago and United Airlines, airports might have more freedom to reward airlines that grow their operations and invest in their city. But it could also allow big local carriers to push out rivals, reduce competition, and set the stage for higher fares and fewer options for travelers.
This is why the O’Hare case is closely watched, not only by those flying through Chicago, but also by airport authorities, airlines, and lawmakers across the country. The court’s decision is expected in June 2025, and whatever answer comes down could set the rules for years to come.
How Are Passengers and the City Impacted?
For most travelers, the maze of airport rules and contracts might seem distant. But the outcome of this dispute could mean real changes to your next trip. Here’s how:
- If United Airlines gets more gates: Expect to see even more United-branded flights, possibly more choices if you’re a frequent United flyer, and more ability for United to connect passengers through O’Hare to destinations around the world. But if American is pushed back, it might eventually mean fewer flight options on American Airlines, especially during busy travel seasons.
- If American Airlines keeps its gates: You’ll likely keep seeing a healthy mix of airlines serving O’Hare International Airport. This usually leads to better competition, more choices, and could keep ticket prices lower than if one airline runs the show.
- For the city of Chicago: The city stands to earn more money and keep its reputation as a world travel hub by making smart deals with airlines. But it also has to follow contracts and keep competition alive, or it could face both legal setbacks and a loss of trust from travelers and businesses.
The Roots of the Conflict: History and Agreements
This situation has its roots in how O’Hare International Airport is run and who has held power over the years. For decades, access to the airport has been handed out through rent and use agreements with airlines. The 2018 Airline Use and Lease Agreement (AULA) was set up to create clear, fair rules. It gives airlines certainty about their access, allows airports to plan big construction and growth projects, and is meant to balance everyone’s interests.
However, these agreements are usually long, detailed, and sometimes hard to change. When an airline believes the city broke these rules, as American Airlines now claims, it can lead to a long, public legal fight. If you’re interested in the fine print of such agreements, or how airport authorities manage airline leases, you can visit the Chicago Department of Aviation’s official website which explains these arrangements in more detail.
Looking Forward: What Comes Next?
With a court hearing set and both sides standing firm, the next few months will tell if American Airlines manages to keep its place at O’Hare International Airport or if United Airlines strengthens its home base in Chicago.
Travelers should watch for news this summer as the final decision comes down. In the meantime, both American Airlines and United Airlines will keep running busy schedules, trying to win over Chicago travelers with low fares and better service.
Whatever outcome unfolds, the lessons from O’Hare will be studied by anyone interested in how airports are managed, how competition shapes travel, and how the smallest of details—such as the number of gates an airline holds—can change the flight experience for millions every year.
In summary, the O’Hare gates conflict is a test of rules, competition, and airline priorities. It is a reminder that what happens behind the scenes at airports directly affects the options and fares available to you. As the case moves forward, all eyes are on O’Hare International Airport, American Airlines, United Airlines, and the city of Chicago, each bringing its own hopes and plans for the future of air travel in the United States.
