List of airlines operating out of Chicago O'Hare Airport

List of airlines serving O'Hare airport

A wide variety of domestic and international airlines with diverse experiences

O'Hare is a major hub for United Airlines and American Airlines, and also serves as a base for low-cost carriers like Frontier Airlines and Spirit Airlines. The airport operates non-stop flights to more than 200 destinations across North America, South America, Europe, Africa, Asia, and Oceania. Reviews of the airline experience at O'Hare vary depending on the airline, terminal, and time of year.

United Airlines operates primarily out of Terminal 1, which has been recently renovated and receives positive feedback for its comfort and efficiency. However, passengers often mention winter delays due to adverse weather conditions. American Airlines, operating out of Terminal 3, is also a significant presence at O'Hare, but passengers have noted that the terminal feels outdated and offers fewer amenities.

Low-cost carriers like Spirit Airlines and Frontier tend to operate out of more congested areas, such as Concourse L, where passengers frequently report crowded waiting areas and limited charging stations. One traveler highlighted that during peak hours, seats in this concourse are scarce, and charging stations are often non-functional, causing inconvenience for those with electronic devices.

International travelers, especially those flying with Lufthansa, have expressed mixed experiences. Although the airport provides a broad range of long-haul flight options, some travelers report overcrowded waiting areas, particularly at busy gates like those for Lufthansa’s flight LH431. Passengers often cite long lines and limited seating as areas for improvement in these terminals.

Passenger Tip:
For a smoother experience, passengers recommend arriving at the airport early, especially for international flights and during winter months. Delays and last-minute gate changes are common, so it is also suggested to use airline mobile apps to stay informed about flight status and gate changes.
