You're finally on your way out for a summer vacation. The flight was booked months ago. Your bags are packed and ready. You arrive at the airport the recommended 90 minutes before the scheduled departure time (because it's a great long trip, and you've decided to check your bags). After enduring the inhumanity that is the TSA line, you get to your gate. Of course, everyone else has done the same thing, and you hear the familiar strains of "this flight is overbooked, we are offering a travel voucher if you are willing to fly on a later flight."

But you ignore that, as always, because, well, your bags are already on the plane, and you don't want to miss even a second of your long-awaited time away. Still, that $300 voucher sounds tempting. You could use it to help defray the cost of holiday travel in a few months.

Don't do it. Resisting that temptation can be even more rewarding: If the worst still happens and you get involuntarily bumped, you can get a full refund of your ticket price plus up to $1,300 in added compensation.
