Spirit Air Seating Assignment Tool

Don’t care where you sit? Spirit will randomly assign you a seat at check-in for free, but we 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).  

Big Front Seats are located in the first rows of our aircraft and feature up to 32% more legroom than the Deluxe Leather Seats. Big Front Seats™ are also wider and do not have a middle seat between them.

Accessible Lavatory for On-board Wheelchair

Spirit offers accessible lavatories on certain aircraft. These lavatories permit a qualified individual with a disability to enter, exit, and maneuver within as necessary, to use all lavatory facilities by means of the aircraft's on-board wheelchair. The two single lavatories located in the aft section are equipped with a feature that allows them to be re-configured or converted into one bigger lavatory to accommodate these customers.   

Spirit seat assignment algorithm (assigned at check-in)

Question for anyone who has ever taken a Spirit flight and *not* paid for a premium seat: could you tell, based on the available seats before OLCI started, what the seat assignment algorithm was?

I will be checking in 4 people on a single PNR next week, MCI-LAS. I will be able to check in exactly at T-24 hours, if that is advantageous. We will be checking 2 bags, so proximity to the front of the plane is not an issue. I'm mainly concerned about whether we will have 4 adjacent seats.

The flight is 100% sold out, but most of the seatmap is available for selection. A vast majority of passengers have *not* prepaid for seats.

Also: my base fare on these tickets is $0.01, total cost of $16 each. Is there any chance that Spirit would not allow me to check in, knowing that we would be among the most advantageous to IDB if necessary? I have had this exact thing happen on Delta, leading to an actual IDB. I'm hoping that Spirit's simplistic systems are more's the last guy checking in who gets hosed.
