There is one catch: Only the very spontaneous need apply.

In order to celebrate its new daily nonstop service between Orlando and BWI, Spirit Airlines is giving away two free tickets on the first flight to Orlando, plus three free nights in a hotel. Were you just thinking, “There must be a catch?” Of course there’s a catch! In order to foster a spirit of spontaneity, Spirit is announcing the winner of the contest at BWI only two hours before the flight takes off this Thursday evening. That means you have to be present at the airport with your bags packed, ready to go, if you’re hoping to win this one.

You can enter by filling out this form, or by just showing up to the Observation Deck at BWI between 3-5 PM this Thursday. Remember: You must be present to win. (And given that Spirit is the one running this contest, make sure you don’t look “suspicious.”)
