How can I earn AA Plat with a single 10,500 mile round trip?</font>
Actually I made a "hang-over" boo-boo-- depending on fare class, 10,000 miles will earn you AA Plat (fare classes H, K, M, Q, W, or V.) If you book in "deep discount" economy (G, L, N, S) you'll only earn Gold on a JFK-EZE-JFK on the same trip.
Info is under "Platinum challenge" on AA board-- very, very simple to sign up.
