I've been bumped twice by ACP's in the last couple months. Both were kind enough to email me a couple days in advance to ask if I would like to get bumped. One was a front end deadhead. I approved both, and appreciated the heads up. Luckily the dead head trip was one that I was over the bank. I had another trip that month that was way under the bank that was paying for my other dead heads. I would have probably declined that bump if offered.
