AAdvantage is the frequent flyer program for American Airlines. It was launched on May 1, 1981, and it remains the largest frequent flyer program with over 67 million members as of 2011. Miles accumulated in the program allow members to redeem tickets, upgrade service class, or obtain free or discounted car rentals, hotel stays, merchandise, or other products and services through partners. The most active members, based on the amount and price of travel booked, are designated AAdvantage Gold, AAdvantage Platinum, AAdvantage Platinum Pro, and AAdvantage Executive Platinum elite members, with privileges such as separate check-in, priority upgrade and standby processing, or free upgrades. They also receive similar privileges from AA's partner airlines, particularly those in oneworld.[48]

The second Admirals Club opened at Washington National Airport. Because it was illegal to sell alcohol in Virginia at the time, the club contained refrigerators for the use of its members, so they could store their own liquor at the airport.[citation needed] For many years, membership in the Admirals Club (and most other airline lounges) was by the airline's invitation. After a passenger sued for discrimination,[51] the Club (and most other airline lounges) switched to a paid membership program.
