We always fly Spirit out of Ft. Lauderdale. Just booked our tickets for April and it was only $370 for two round trip tickets. I've priced out Caribbean Air vs. Spirit and even though Spirit charges for baggage, etc., it still worked out to be a better deal. Also, I posted a thread about this but just learned that if you book your tickets at the airport counter (in advance -- not day-of) that you can save quite a bit of money. There is a hidden convenience fee that they charge online called the "passenger usage fee" that you don't get charged if you buy at the airport. I saved $70 by doing this. I just had a friend drop me off and circle the airport until I was done. It was Christmas Eve and it didn't take more than 30 minutes. Some airports have free short-term parking or nominal charges for an short amount of time. According to reports online, this works for other airlines as well and you can try calling them in advance to see what the airport price would be.
