Hi -- I have $200 in travel bank (thanks, Amex) and $50 in travel credit (thanks in-seat monitor that didn't work but kept waking itself up with a super bright screen in order to wake ME up on a red-eye flight). I haven't paid cash for a ticket in a while, but now I have the opportunity to do it. I know you can't really use both. I read about a potential workaround where you book a regular economy ticket using travel bank, cancel after 24 hours, it becomes travel credit, and then, voila, I could use all $250 for my flight. Are there any red flags here for me? The $50 expires first, but if there is any chance of really messing up the $200 or not being able to do this, I would just use the $200 and forfeit the $50 I guess (there's almost no chance I'd ever use it). Thanks.
