Still looking for a last-minute gift idea? Here’s an affordable item that everyone in your family will be fighting over: As Travel + Leisure reports, JetBlue is selling a $20 board game that includes complimentary round-trip airfare.

The object of the limited-edition game, called Get Packing!, is to fill up your board with personal belongings in preparation for your flight and prevent other players from doing the same. Sounds simple enough, but if you play the way JetBlue recommends, the gameplay will get competitive fast: The first person to fill their bag wins a certificate that can be redeemed for a real round-trip flight.

Winners have from January 1, 2018 to December 31, 2018 to book their free trip. Destinations eligible for flights include domestic cities as well as ones abroad, like Quito, Ecuador and Lima, Peru. Taxes and other fees apply and travelers will still have to pay blackout rates on busy travel days.

After debuting the deal on Amazon on December 12, the product quickly sold out. Fortunately, a new batch will be made available on December 18 at 3 p.m.—just remember to act fast, as it’s likely to be a hot item on everyone’s wish list.
