I think Kitty Hawk snags second place with the $200 and 75 minute earlier arrival. Good deal there.
AAPlat pretty much nudges me out with the $500 for an hour (now, now, my delay was only fifty minutes!), but he got an upgrade, too. Lucky dog.
Back in '93 or '94 I was bumped from a SWA flight and received a $200 voucher. My other flight got in 10 minutes ahead. Sadly, Kitty's still beats my gig!
