No, the kind of bumps we like. We volunteered to give up our seats on our short flight from San Francisco to Seattle and were rewarded with two domestic ticket vouchers for being "bumped." It's actually been pleasant hanging around the San Francisco Red Carpet Club for the past few hours with a lunch break as well and we'll still be landing in Seattle by 8:00 p.m. or so.
Not a bad day's work for a couple of retired folks.
Update: Or, as United calls it, EasyUpdate Travel Alert received on our wireless and e-mail at almost exactly the moment we posted this. Our flight will be leaving at 6:55 p.m. instead of 6:15 p.m. That's no big deal, although sometimes these delays have a way of mushrooming.
