From what I have read, if you volunteer to leave they can pay you in flight vouchers. The worth of these is lessened by the fact they would give you $300 as 6x $50 vouchers which cannot be used at the same time. If they elect you to leave the flight they have to pay you in cold hard cash - 4x the ticket value or $1350 max (assuming you are delayed by more than 2 hours). Never volunteer to leave a flight until they state how you will be paid. In Europe the airlines are not allowed to pay you in vouchers.
