JetBlue has an enticing offer for anyone resolving to travel more in 2018: Customers who book a non-refundable flight before December 15 will be automatically entered to win the airline's All You Can Jet Pass, Thrillist reports. That means a full year of free unlimited flights to 100 destinations in the U.S. and beyond.

If you already have, or are planning to, purchase a flight in the first half of December, no further steps are required: You're automatically in the running to receive one of the three available passes. And if you have no upcoming flights to book but a bad case of wanderlust, you’re also invited to enter. To do so, just mail a letter with your full printed name, address, phone numbers, and email address to: All You Can Jet Sweepstakes, Centra 360, 1400 Old Country Road, Suite 417, Westbury, NY 11590.

The randomly selected winner can start flying for free as soon as February 1, 2018.

All You Can Jet Pass flyers won’t be able to book multiple flights departing from the same city on the same day, and change and cancellation fees will still apply. Other than that, they can travel without limitations. Travelers get a complimentary plus-one for each flight they book, and they’re free to change their travel companion from trip to trip. There are zero blackout dates, so even on the busiest travel days of the year, winners can fly without paying a cent.

The free year of travel ends January 31, 2019. If they’re smart with their time, it’s possible for winners to visit every one of JetBlue's 100 destinations, including Jamaica, Los Angeles, and the Dominican Republic, by the time their pass expires. The only thing they'll need to worry about is finding the energy for all that travel.
