Key Takeaways
• United Airlines seeks six more gates at O’Hare, citing its 52% flight share but only 48% gate access.
• American Airlines filed a lawsuit against Chicago, claiming premature gate changes violate the 2018 master lease agreement.
• A final court decision, expected in June 2025, will determine future gate distribution and airline dominance at O’Hare.
A high-stakes fight is shaping up at Chicago’s O’Hare Airport, one of the world’s busiest airports, as United Airlines and American Airlines struggle over valuable gate space and the future of air travel in the area. Both carriers see Chicago 🇺🇸 as a main hub for their businesses, and these disagreements could shape not only their own operations but also the choices and prices for travelers, the local job market, and even the city’s economy.
The Heart of the Dispute: Who Gets the Gates?

At the center of the struggle is a planned change to how gates at O’Hare Airport are divided and shared between the two big players, United Airlines and American Airlines. Gates are where planes park, load, and unload passengers, making them one of the most valuable resources in any airport.
United Airlines says it carried out more than half of all flights leaving O’Hare last year, specifically 52%, but it only has access to 48% of the gates. The airline now wants six more gates, which would allow it to run even more flights. But these gates would have to come from American Airlines’ share.
American Airlines currently holds 41% of all gates at O’Hare but only operates 37% of the airport’s departures, based on numbers provided by United. According to proposed changes, United’s gate share would increase slightly, from 40% to 42%, while American’s would fall from 30% to 28%. These changes would come into force starting October 1, 2025.
It’s not just about numbers. Gates enable airlines to schedule more takeoffs, attract more customers, and become the first choice for travelers. Losing gates can limit an airline’s ability to grow. For United Airlines and American Airlines, this means a lot is on the line.
The Lawsuit: American Airlines Takes the Fight to Court
Facing the loss of valuable gates, American Airlines has responded with a lawsuit against the city of Chicago 🇺🇸. The central issue is the timing of the gate changes. American Airlines argues that Chicago city leaders acted too quickly, moving to reallocate gates before certain construction in the L gates area was finished. They claim the final work wasn’t completed until late March 2025, which they say means the process was triggered too soon and violates the rules set out in a master lease agreement signed in 2018.
Specifically, American Airlines argues that this “improper trigger” breaks the agreement all parties signed, which was supposed to decide how and when gate changes could happen. The lawsuit is now moving through the courts. According to analysis from VisaVerge.com, such lawsuits can delay or even block changes in airports, affect future agreements between airlines and cities, and add a legal element to what is already a fierce business rivalry.
A decision in this case is expected by June 2025. What happens in court will play a huge role in determining whether United Airlines gets the extra gates it wants or American Airlines gets to keep them.

More Than Just Lawsuits: How the Airlines Compete Day-to-Day
While the legal challenge moves ahead, both United Airlines and American Airlines are busy trying to win over travelers and keep their market power in Chicago 🇺🇸. They’re not just waiting for the courts. Both are using bold moves on the marketing front and changing their business plans to outdo each other, making the scene at O’Hare Airport very lively.
United Airlines’ Recent Moves
United Airlines has started a smart local advertising campaign right in O’Hare Airport. Travelers now see signs and posters claiming United is “Chicago’s #1 airline.” This isn’t just a slogan—United wants everyone, including travelers, business partners, and staff, to see them as the main airline for the city.
They are also inviting people who usually fly with other airlines (including American Airlines) to switch by offering special deals, like their Premier status challenge. This is a type of program that lets loyal travelers get special perks if they try flying United Airlines for a set time. The airline also highlights its larger number of flights, more international destinations, and fancier airport lounges.
Recent upgrades at O’Hare include a reopening of United Airlines’ Polaris Lounge, used by premium and international travelers. With more seats, new amenities, and improved food and drink, United hopes to win over business and frequent-flying customers.
American Airlines’ Response
American Airlines is not backing down. The airline is pushing forward with its own growth plan for O’Hare in 2025. One executive described American’s efforts as being in the “fourth inning,” reminding people that while they may not lead in Chicago 🇺🇸 today, they’re committed to building up over time. Even as the company admits it will “probably always be second-place in Chicago,” the message is clear: they plan to grow, adding more routes and better services for travelers.
American believes that having two strong airlines at O’Hare is best for travelers, as it leads to more flights and better prices. Their strategy is focused on reinforcing their presence through more flights, customer perks, and business partnerships.
Why Does This Matter? The Bigger Impact
This gate battle at O’Hare Airport affects more than company profits. It has major consequences for travelers—people like you trying to get to Chicago 🇺🇸 or use it as a stopover to other cities and countries.
Travelers
- Choices: Travelers often want as many flight options as possible. More gate space for one airline can mean more flights, but if the second airline shrinks, it can result in fewer choices for certain destinations.
- Fares: Strong competition between United Airlines and American Airlines can help keep ticket prices down. If one airline gets too much market share, there is some risk of fares rising.
- Quality of experience: Upgraded lounges (like United’s improved Polaris Lounge), more flights per day, and special status perks can make using O’Hare Airport more pleasant.
Business and Local Economy
O’Hare Airport is a key gateway for trade, business meetings, and tourism. When airlines fight for dominance, it can affect:
- Job creation: More flights can mean more jobs, both for airline staff and airport workers.
- Business investment: If O’Hare offers good connections, more companies may choose to set up offices or hold meetings in Chicago 🇺🇸.
- City competitiveness: The city’s leaders want O’Hare to offer as many routes as possible, keeping Chicago at the center of US and worldwide transportation networks.
What Each Side Is Saying
United Airlines feels that its bigger share of flights justifies getting more gates. Their reasoning is simple: if they operate over half of all flights, they should get more space to grow. United is making changes quickly, adding 10% more seats in summer 2025 than last year and planning to offer up to 23% more seats than American Airlines between June and August.
American Airlines strongly opposes the changes, insisting that removing gates from their share would slow their growth and reduce competition. American’s leaders also say that having two major airlines at O’Hare benefits the city—it means more flights are available to more places and keeps Chicago 🇺🇸 important for business. The lawsuit is not just about gates—it’s about the power to shape the future of air travel at one of the most critical airports in the country.
The Legal and Political Landscape
The outcome depends not just on legal questions but also on city politics and long-term contracts between airlines and the City of Chicago 🇺🇸. American Airlines points to a master lease agreement signed in 2018, arguing that it clearly spells out when gate changes are allowed. By reallocating gates before construction was fully done, they say, the city broke that agreement.
This kind of contract, very common in airport management, is key to making sure all airlines are treated fairly and that changes to important resources like gates are not made in an unfair or sudden way.
If the court agrees with American Airlines, the planned changes could be postponed or stopped. If United Airlines wins, it could get a step ahead in one of the world’s oldest airline markets.
Looking Ahead: June 2025 and Beyond
A final decision is due in June 2025, and whatever happens will shape travel out of O’Hare Airport for years to come. People who use the airport can expect to feel the effects right away—through changes in airline schedules, possible ticket price shifts, and a different feel to their travel experience.
Both United Airlines and American Airlines recognize what’s at stake. This is not just about next year’s business plans—it’s about setting up Chicago 🇺🇸 for the next decade. As each carrier makes its case through courts, media, and marketing, travelers and the local economy watch closely.
