Did you ever book a flight knowing it was, overbooked/bad weather/possibility of cancellation, inorder to get bumped and get, miles/points/money/free upgrades?
Almost, was in the airport picking someone up (got to gate using club card, thanks dan) and the gate next door was asking for volunteers. I thought of making a award tix even for 25,000 one way, Get bumped, then cancel the award tix.
