Spirit is basically giving away tickets over Christmas and New Years. Their "No Excuses Sales" has tickets starting at $19 one way with no ticket more than $59 one way. We did a few searches and turned up flights from Orlando to Jamaica for $118 and New York to Bahamas for $169 after taxes. The details:

Spirit Airlines thinks that there should be no excuses why you can't travel this winter, and just to prove it we are giving you fares as low as $19* each way! With no sale fare over $59* each way, there should be no excuse why you can't be home with your family over the holidays, escape the cold weather and take a Florida or Caribbean vacation, or do both!

These phenomenal fares are based on a roundtrip purchase, and must be booked by 11:59PM EST on Sunday, December 18, 2005.
