If anyone figures out the actual rules for cancelling Frontier award travel, please post them. I'm thinking of using my points for the Caibbean next year, but haven't given it much thought yet. Domestically, the longest nonstops I can do from the East are to Vegas, and they've been selling me seats for $39, so award travel seems silly. I try to avoid booking Frontier connecting travel, as that didn't go well for me.
