Chicago O'Hare is one of the world's busiest airports and a major hub for domestic and international travel, so its lounge scene is large, but the part that matters for membership holders is concentrated in the international terminal. Knowing where the Priority Pass lounges are before you go saves a long walk in a very big airport.
Priority Pass lounges at O'Hare
The Priority Pass lounges at O'Hare are in Terminal 5, the international terminal. There are two: the Air France Lounge, which opened in Terminal 5 in late 2025 and is the higher-quality option for design, food, and overall experience, and the Swissport Lounge, also in Terminal 5, near gate M13. If you are flying internationally from Terminal 5 and hold a Priority Pass, the Air France Lounge is the one to aim for, ideally earlier in the day. Note that these Priority Pass lounges are in the international terminal, not the domestic terminals 1, 2, and 3.
Access methods and cards
Beyond Priority Pass, many travel rewards cards include a Priority Pass Select membership: for example, the Chase Sapphire Reserve gives complimentary Priority Pass Select, which includes two guests per visit. O'Hare does not currently have a Chase Sapphire Lounge, so do not plan around one. The domestic terminals have airline lounges, such as United Clubs, for those airlines' passengers and members, but they are separate from the Priority Pass network. So match your access method to your terminal: Priority Pass works in Terminal 5, while airline lounges serve the domestic terminals.
Amenities and tips
The Terminal 5 Priority Pass lounges offer seating, food, drinks, and Wi-Fi, with the Air France Lounge the more polished of the two. Because O'Hare is enormous and Terminal 5 is the international terminal, factor in walking time and terminal transfers when planning a lounge visit, especially if you connect between domestic and international terminals. Confirm your lounge and access method before you travel, and use the comparison below to match a membership, a card, or airline status to the right lounge.
