Does anyone know about or has anyone tried the following? Purchase a full-fare ticket for a (hopefully) overbooked flight, offer to give up your seat, collect vouchers, let the plane you were *supposed * to be on leave, return to ticket counter, have ticket refunded. Does this work? Is this ethical? I've got a weekend to kill, and I thought it might be fun to pick up a few hundred dollars worth of vouchers. THanks!
