I agree that bumping another passenger to make room for my son would have made for 2 unhappy passengers. But by that logic, if the next 3 flights out of Was.Dulles had been overboooked, then my son would have been stuck there another day. I still maintain that NO airline should just keep rescheduling the already inconvenienced passenger until a seat on some flight opens up-however long that takes. Bumping a passenger from the 10:30 flight to a 3:00 p.m. flight the SAME DAY is a hell of a lot less inconvenient than bumping my son-or anyone-from 4:30 p.m. one day till 3:00 the next day, no matter how you look at it.
