On top of no shows..travel agents also book certain of their top passengers on more than one flight on a given day..I have pulled up JFK to LAX passenger lists and seen the same individual booked on four or five flights. then no matter what flight they can make, they have a seat. Not only are they sticking it to the airline because those are seats that can be sold but when they also list them for upgrades they are sticking it to the rest of the top tier members of any given airline. Also, I don't know about any other airlines but I have never seen an AA flight oversold in FC
