If you are an American Airlines loyalist and have an Admirals Club lounge in your home airport then this card is for you. In addition to unlimited lounge access to American lounges, this card comes with a number of valuable benefits for AA frequent flyer.
The Admirals Club lounge membership alone is worth over $800, so you should have no problem justifying the $595 annual fee (especially when you take the signup bonus and other AA perks into account).
Want more than just the Admirals Club lounge?
