JetBlue is giving three lucky travelers the chance to fly for free — for an entire year — with their All You Can Jet pass, and today is your last chance to put your name in the proverbial pilot’s hat.

When JetBlue first dreamed up the All You Can Jet pass in 2009, it was available for the cool (and totally worth it) price of $599. They auctioned off remaining passes in 2010, before turning the passes into competition prizes in 2014.

There are two ways to enter for your chance to win unlimited trips to any JetBlue city for an entire year.

One entry into the competition is made for every traveler who books a non-refundable flight directly through the airline by December 15. Round-trip flights count as two entries.

But you don’t have to book a flight for a shot at the All You Can Jet pass. Travelers can also mail a hand-printed entry for free (with sufficient postage, of course). Letters must be postmarked by December 15 and received by December 22 to be considered.

JetBlue will announce the recipients of the All You Can Jet pass on December 27.

All You Can Jet passes apply to the winner and one selected friend or family member, which can be changed at any time. There is no limit to the number of flights that can be taken, though winners cannot book two flights out of the same city in one day, or use the pass to purchase premium seats.

For more information about entering, JetBlue has provided official rules and a comprehensive FAQ about the sweepstakes.
