My two UA bumps last year were for $200 each; the first was a UA commuter flight between SAN-LAX. I was confirmed on the next flight, which was only 30 minutes later; so it was a great deal for $200. The next involved rerouting; I gave up my ORD-SAN seat for $200 and about 20 of us were rerouted ORD-SFO-SAN. They also promised a lunch voucher but by the time they had reticketed 20 people we had to rush over to the other concourse & just barely made the SFO flight. If I had to do it over again, I'd skip the ORD bump as I gave up my nice Premier-zone aisle seat on a 757 for a window seat way at the back of a 777 plus a crappy Shuttle flight that made me check my carry-on bag to get $200..
