Whether you’re connecting through Los Angeles or taking a domestic-only hop, a Qantas Gold or Platinum card can get you into American Airlines’ best lounge.

Qantas has lined up its lounge of choice in Chicago, should its Brisbane-O’Hare route make it back onto the schedule. I stopped by to see what awaits in the Windy City.

With AA offering two tiers of airport lounges, it pays to know your options in the United States, and when you can access each one.

Being a hybrid of domestic, international, Business and First Class, the Flagship Lounge is a real catch-all. It’s also where most of Qantas’ premium passengers venture before flights to Australia.
