The American Airlines Flagship Lounge at Chicago O'Hare is a comfortable and well-appointed lounge that is exclusively available to American Airlines and oneworld premium and elite customers travelling internationally. It features a generous food and beverage selection that would make Admirals Club guests envious.
The Flagship Lounge has fantastic views of the runway and is a convenient spot to work, although it lacks true seclusion and can get crowded during peak hours. The hometown airline has a full a-la-carte restaurant, a staffed bar, and private napping rooms among other pleasures, so it can't quite compete with United's Polaris Lounge in terms of amenities, but it is still a significant increase for business class and premium travellers.
