Spirit's A319 aircraft flies in a one class configuration with 145 seats of Economy Class. Spirit Airlines refers to their Economy Class as "Deluxe Leather" seats.
Spirit's A319 aircraft feature seats with 28 inches of seat pitch - the least amount of space of all US domestic carriers. Spirit's A319 offers 10 "Big Front" seats which are larger seats at the front of the cabin. These "Big Front" seats offer an additional 6-8 inches of extra legroom and wider seats in comparison to the standard "Deluxe Leather" Economy seats. These seats are available to passengers at an additional fee.
Spirit charges to reserve seats per one-way segment. These fees will vary depending on duration of trip and whether the seat is an aisle, middle or exit seat. Seats may also be reserved for the same fees at time of check-in. If no seat preference is made, one will be randomly assigned at the airport or during online check-in. Seat fees are non refundable and may not be changed once a boarding pass is issued.
