I've been bumped a few times--I'm usually pretty flexible with my travel plans, so I always jump at the oppt'y...
STL to DCA on TWA--attended a big medical conference, flight was overbooked by about 10 people. ended up with a free RT voucher and got in only 2 hours later.
New Orleans to DCA on NW--had volunteered to give up my tix; they initially said they didn't need me, but then--once I was on the plane--the lead FA came up and asked if I'd like to give up my seat. got $500 credit voucher and was rebooked on another airline.
SLC to BWI on United--got $300 voucher; almost got another one in denver (where I rerouted through); ended up with 1st class seats to BWI
