A couple of months ago a friend and I were booked CVG-FRA on a Friday night. He's a PM and I a GM. We discovered that the flight was overbooked by 34 seats 1 1/2 hours before departure. We volunteered to be bumped. They bumped us both, gave us a $500 voucher, $15 meal ticket, Hilton hotel for the night, rebooked us BizElite RT for the next day's flight;we were in L class on a nonrefundable, nonexchangeable, non upgradable ticket. They were pleased that we were willing and needless to say we enjoyed it thoroughly as we were on inexpensive Escape fares. We both really like DL and get upgraded fairly regularly but not bumped very often as planes are rarely full. We heard later that BE may not have been full the night of our original reservation after all.
