Like many FTers, from time to time I have been wait-listed on ordinary none-RTW flights for, say, a business-class seat. If one became available on the night, I flew, otherwise I waited for another flight or flew further back in the a/c.

Does a similar possibility exist for AONEx & DONEx reservations? Looking at flight inventories in the last day or days before a flight, it's not unusual to see F4 A0 or J9 D0. I guess Revenue Management is holding out for last-minute F or J pax, which is their job. All the same, I'd be happy to take my chances on the wait-list in many circumstances. Does anyone have specific experience in this area? When you wait-list, is it for a seat in the x cabin, or is it still based on booking classes?

TIA.
