A Spirit Airlines boarding pass can be printed online after checking in. This is done up to 24 hours before the time of departure. During check-in online, Spirit Airlines allows for purchasing extra space for bags or seat assignments.
Spirit Airlines also has airport kiosks for checking in and printing a boarding pass. This is a good option for people who don't have access to the Internet before their flight, or who were not able to print the boarding pass due to printer issues. There are also customer service desks at the airport that allow you to check in manually, though this is the longest wait time. When using a counter to check-in, there is a $10 charge to print the boarding pass, explains the official website.
