In the past few years I have found that when I fly EL AL if they are overbooked and you ask if they are overbooked and volunteer to be put on a later flight they will give you a free round trip ticket good for travel to Israel from anywhere in the world. Somebody just told me that you can do the same thing with BA. I am curious if how many other airlines have the deal and which ones overbook the most?

As a student I normally am in no rush to go anywhere and would gladly do this every time I fly. Last time it happened I was going from TLV-EWR and got bumped to an hour later flight on AF which had a few hour stop over in Paris... a round trip ticket on EL AL is about $1300 if you're lucky.
