There used to be an American Airlines Admirals Club on the “E” concourse of the Miami airport. Nearly all of American’s flights out of Miami depart from D these days, so the Admirals Club closed in E. There are still some American flights out of E, and some oneworld partner flights, so the lounge was re-opened several years ago as a shared oneworld lounge though officially it’s designated the “premium lounge.”
However, the American Airlines club newsletter reminded of a recent change to this policy. Admirals Club members can now access this premium lounge which has ample seating as well as better food and liquor.
