United Airlines and American Airlines are two of the biggest names in the airline industry, and both have a strong presence at Chicago O’Hare International Airport. However, as of early 2025, United Airlines has taken a clear lead over American Airlines at this important hub. Let’s explore how this happened, what these changes mean for travelers, and how each airline is responding to this shift. We will look at market share, gate allocation, route options, customer experience, and what experts say about their future at Chicago O’Hare.
United Airlines: Market Share Leadership at Chicago O’Hare
Starting with market share, United Airlines now controls about 40.6% of the flights at Chicago O’Hare. In comparison, American Airlines holds about 22.8%. This difference is important because it shows that nearly double the number of passengers choose United over American at this airport.
This gap is the widest it has been in recent years. Back in 2019, the lead was much smaller, with United being only six points ahead. By the end of 2024, that difference had increased to 22 points. This widening lead tells us United is not only keeping its core customers but also winning over more local travelers who may have used other airlines before.
United’s advantage started to grow quickly after the pandemic, picking up more business as travel returned. American Airlines, in contrast, has not been able to regain the same amount of flights or seats it once had before the pandemic. This trend is important for anyone who travels frequently via Chicago O’Hare, since United’s larger share may result in more choices and better deals for passengers.
Gate Allocation: United’s Critical Jump Ahead
A big part of why United Airlines has jumped ahead comes down to access to more gates at Chicago O’Hare. In April and May 2025, United got six more gates during a major airport expansion. This move makes it easier for United to offer more flights, especially during the busiest travel hours.
Getting new gates is important for any airline because gates are limited. Without enough gates, airlines cannot add new routes, more frequent flights, or bigger planes. For United, these added gates support their “United Next” growth plan, which is focused on expanding rapidly and taking advantage of new opportunities as the airport grows.
The decision by Chicago officials to give these gates to United instead of American Airlines has had big consequences. American Airlines did not stay silent—they started legal action, saying the city broke old agreements and hurt fair competition. American’s leaders argue that it limits their ability to grow, possibly forcing them to stay small while United keeps getting bigger.
This legal fight shows just how important control of gates is for airlines. Without enough gates, American Airlines struggles to add new services or compete with United at Chicago O’Hare. For travelers, the airline with more gates can usually offer more flights and destinations, which means greater flexibility and better service.
Network Strength and Passenger Experience
Besides market share and gates, United holds a strong advantage when it comes to the number and range of flights it offers. United provides more total flights and more international destinations from Chicago O’Hare than any other airline—including American Airlines and Southwest Airlines. This is really important for travelers who want to reach cities around the world without needing to connect through other airports.
Business travelers, in particular, value these wide options. United’s larger network allows them to fly directly to more places, saving time and reducing travel stress. United also has more lounges at O’Hare, giving travelers nicer places to relax or work before flights. These lounges are especially useful for frequent fliers and people who spend a lot of time waiting due to layovers.
Another part of the experience is on-time performance—how often planes leave and arrive as planned. United is often seen as more reliable in this area. For business travelers and families who hate waiting around, knowing that their flight is likely to be on time can be a deciding factor in which airline they pick.
United’s investments in updates at the airport—like a modern headquarters and new lounges—help them keep this customer-focused edge. Many of American Airlines’ airport areas still look older and less inviting to travelers.
Branding and Local Identity
United Airlines is not just another airline at Chicago O’Hare—it tries hard to make travelers feel this is “their” airline. United’s headquarters is in Chicago, making it feel local and familiar. Beyond just running flights, United is deeply connected to the city. For example, it has the naming rights to the famous United Center arena, where many local sports teams play.
To build on this relationship with Chicago, United has started a special marketing campaign just for people in the city. They put up new, very visible signs at the airport and even advertise using the label “Chicago’s #1 Airline.” This helps United stand out and develop loyalty among local travelers, many of whom prefer to support companies rooted in their city.
As reported by VisaVerge.com, United is making a clear effort to be the first choice for anyone flying in or out of Chicago. The company is banking on the connection Chicagoans have with their “hometown” airline, which can be a strong reason why travelers choose United over other carriers.
American Airlines: Playing Catch-Up
American Airlines is clearly behind United at Chicago O’Hare, but it is not giving up. To try to narrow the gap, American recently announced seven new routes for winter 2024–25, including direct flights to international cities. The aim is to offer places that United and other airlines do not serve directly from O’Hare.
On top of that, American is increasing how many times it flies on 10 existing routes. This increase in flights could help American regain some passengers lost after the pandemic, when it was forced to cut back on both the number of routes and overall flight seats.
Yet, for all these new announcements, American is still limited when compared to United. The legal fight over gate allocation is a big deal—if American cannot get more gates, its ability to add routes and increase flights is blocked. Also, while American promises not to lose any more ground to United, there is no sign yet of big investments in newer lounges or major upgrades to their airport sections at O’Hare.
This means that, for now, American Airlines may win back some travelers with new destinations, but its competitors, especially United, will keep many of the advantages that matter most to customers.
Head-to-Head Comparison: Key Differences
The following table presents the most important differences between United Airlines and American Airlines at Chicago O’Hare:
| Metric | United Airlines | American Airlines |
|---|---|---|
| Market Share at O’Hare | ~40.6% | ~22.8% |
| Additional Gates Gained (2025) | +6 | None |
| Local Passenger Lead (Q4 2024) | +22 points ahead | – |
| International Routes/Lounges | Most at O’Hare | Fewer, but expanding |
| Facilities Investment | Modern upgrades, new lounges, marketing | Slower, older concourses |
These details make it clear why United is ahead. More gates mean United can run more flights and reach more destinations. A bigger market share shows more people trust United at Chicago O’Hare, and better facilities make the flying experience more comfortable for travelers.
Pros and Cons for Travelers
United Airlines
Pros:
– More flights and a wider network (especially international).
– Modern facilities and more lounges.
– Often better on-time performance and reliability.
– Strong local ties and brand presence in Chicago.
Cons:
– The bigger an airline is, the harder it can be to keep every customer happy.
– With more flights and people, lines may sometimes be longer.
American Airlines
Pros:
– New routes, especially to places competitors might not serve.
– More choices and higher frequency on some existing routes.
– Competing hard to improve and win back customers.
Cons:
– Fewer gates limit growth opportunities at O’Hare.
– Facilities not as new or appealing as United’s.
– Smaller network overall at this airport.
Trends and Outlook
The trend at Chicago O’Hare is clear: United Airlines has increased its lead over American Airlines more than at any other point in recent years. This is thanks to smart use of new gates, bigger investments in customer experience, more direct international flights, and a strong local connection built through both marketing and community involvement, as shown by their visible presence at the airport and around the city.
While American Airlines is trying to catch up with new routes and legal challenges over gate assignments, these moves alone may not be enough. Unless American can either win more gates in court or convince the city to invest more in its facilities, it will stay in the number two spot for the foreseeable future.
Experts say that the advantage United now enjoys is likely to continue unless there is a big change—either in government policies, major airport changes, or dramatic business decisions by American Airlines.
Real World Impact: For Travelers and the City
For regular travelers, this means that if you fly through Chicago O’Hare, you are likely to see more United Airlines logos, more United flights to choose from, and newer lounges to relax in before your trip. If you travel for work, those extra options and better reliability can help you get where you’re going with less stress.
For American Airlines passengers, there are still many good options, especially as new routes are added. However, features like new lounges, less crowded check-in areas, or a wider network may take time to arrive.
From a city perspective, Chicago benefits from having a “hometown” carrier that invests in the airport, supports local jobs, and brings more choices for business travelers and tourists. This competition can also push both airlines to keep improving.
Case Example: The Gate Reallocation Battle
United’s 2025 gain of six new gates was not just a simple expansion. It shows how airports and cities make choices that can shape the competition between airlines for years to come. American’s legal action shows how high the stakes are. If American loses, it may not be able to catch up anytime soon. If the city has to give American more chances, travelers could benefit from even more competition. For now, the deck is stacked in United’s favor.
Conclusion: What Happens Next at Chicago O’Hare?
United Airlines is clearly winning the tactical battle at Chicago O’Hare. With the most flights, best facilities, and strongest brand in the city, United is the first choice for many travelers. American Airlines is working hard to stay in the fight, using new routes and legal challenges to stay relevant, but unless things change, United’s lead may only grow.
Travelers who want to keep up with route launches or facilities improvements should check updates from the City of Chicago’s official O’Hare Airport information page, which regularly posts news on airline expansions, gate assignments, and airport upgrades.
Whether you are a frequent flyer choosing between United Airlines and American Airlines, or just someone interested in how big companies compete, Chicago O’Hare is a prime example of how strategy, investment, and local identity shape the way we travel. United’s story at O’Hare is a lesson in how to turn advantages into lasting leadership—until the next big change arrives.
