I'm not sure where to ask this question so feel free to move it to the appropriate forum. We have a trip to Las Vegas planned and decided to try and extend our trip (non-refundable tickets of course). We know the return flight is full, probably oversold. If we volunteer to be bumped, do we have to take the next scheduled flight that has space or can we ask for a return several days later? There are obvious advantages to doing it this way although I realize our success is not guarenteed.
