I'm currently approaching 2.6MM lifetime on AA, after hitting 1MM in Nov 2001 and 2MM in Nov 2004 (I'm behind schedule for hitting 3MM!!) A big chunk of the 2MM was from the Cinemark promotion several years ago; large soda cups had 100 AA mile stickers on them. I spent several days going through movie theaters after the shows let out, pulling stickers off of cups people left! Hit 1MM when exchanging electronic upgrades to miles, and 2MM on a LGW-DFW flight.
