On Aug. 29, FlyerTalk.com made history — again.

FlyerTalk, the world’s largest online community of frequent flyers, reached its 2 millionth post.

To celebrate the occasion, FlyerTalk founder Randy Petersen awarded $500 in cash and 10,000 bonus miles to the FlyerTalker who guessed the precise moment the 2 millionth post would appear. “Gregseattle” turned out to be the big winner, correctly guessing 4:20 p.m.

FlyerTalk was started over five years ago, and provides frequent travelers a forum to share information and ideas about their favorite (and less-than-favorite) loyalty programs.
