Don’t care where you sit? Spirit will randomly assign you a seat at check-in for free, but Spirit Airlines can't guarantee that you'll get to sit with your friends or family. You can purchase a seat assignment and choose the seat you really want. Seat assignments start at just $5 and vary according to specific routes and location in the aircraft. For a little bit more, a Big Front Seat™ comes with extra legroom.
You can view seat prices for your flight on the Seats page when you book online, in My Trips or Online Check-in (within 24 hours of departure).
