Last day to join the American's Most Elite Frequent Flier Club!
"Membership in Concierge Key is usually limited to American’s highest spenders and most frequent fliers. It’s so secret and exclusive that the airline doesn’t even list it on its website.
Once they’re in, members get airport escorts, a dedicated concierge service that handles upgrade requests and re-booking privileges, automatic Executive Platinum status, access to the Admirals Club and Flagship lounges, complimentary international upgrades, as well as two system-wide upgrades. They also get VIP check-in privileges at Flagship Check-In in select airports."
