DON'T DO IT! If 1 thing goes wrong, even through the airline, you WILL lose your money. UPDATE: Trying to rebook a flight with my future travel credits from my canceled flight and now being told there's a $45 PER TICKET fee to rebook. 2ND UPDATE: 5 hours of lies back and forth (through email because it's 1993 at Hopper) under the guise of "miscommunication", I just took the rebook with hidden "class change" fees despite booking the same class. I just don't have the time for them. Good luck.
