Just in time for Caribbean travel season, JetBlue today kicked off service between New York’s JFK and St. Lucia. We’re big fans of the blue airline, so it’s exciting to see their destinations expanding. It’s even more exciting to see the kickoff deal: only $129 each way. Sure, there are strings attached: you have to act fast (book by this Friday) and travel between November 2 and February 8, 2010 (yeah, Valentine’s Day is going to cost more).

It’s a great deal to one of our favorite islands. Get beyond the beaches and snorkeling and you'll find myriad activities, like climbing Petit Piton, going to the Friday night Jump Up party, and mountain biking through the jungle (on the grounds of Anse Chastanet Resort).

Of course, you can stay at Anse Chastanet as well, one of three World's Best Hotels on St. Lucia (Jade Mountain, Anse Chastanet, and Ladera, in order of voting). Or book into an up-and-comer like Stonefield Villas (pictured), where each of the 17 villas has its own plunge pool and a view of Petit Piton. And like with JetBlue, you'll find a deal here, too: book direct and get 50% off midweek nights through December 21.
