Get on a Flight to Fort Lauderdale and if you time it right you can grab a flight out of FL on Spirt, I know, I know Spirit doesn't have a great reputation but our flight to SXM was $57.00 Return was $108 with one free checked bag. Plus we chose the exit row seats and got plenty of stretch room for $15.00 more. It's less than a 3 hr flight so I can put up with that for $57.00
