Your ticket includes the option to bring one carry-on bag, which fits in a box about the size of a backpack. Anything larger, such as a larger carry-on bag, must be purchased. The price varies from when you decide to purchase the extra bag, but if you decide to purchase it at the same time as your ticket, the price ranges from $39.00 to $98.00.

Check-in can be done online or in person. Online check-in is the fastest way to check in, and both check-ins begin 24 hours before your flight's departure. If you check in at the airport, you'll have to pay $25 to print your card.

If you don't mind where you sit, Spirit Airlines may randomly select a seat, but the company doesn't promise you'll be seated with your friends that way. Of course, you can choose one for yourself so you'll be sure of where you sit.
