I actually fly Spirit quite a bit, but it's all of the $9-fare variety, and I can go anywhere I want as long as it's FLL. I'm in the $9FC but don't have the credit card, so it's looking like a treadmill of getting a few thousand miles and just having them expire on me, thanks to Mr. Expire-Those-Miles Baldanza.
Assuming I don't get the credit card (or they don't want me to get it), is there any use for two or three thousand Spirit miles? I'll happily take magazine subscriptions or even a free junk fee or two on the next flight. Anything?
