Hello, If you're asking, does spirit have assigned seats, the answer is yes. On my last trip with Spirit Airlines, I noticed they assign seats randomly for free during check-in. However, if you want to choose your seat in advance whether aisle, window, or extra legroom you have to pay an additional fee. I personally paid to sit closer to the front for a quicker exit. The option to select is helpful if you're traveling with family or want specific seating. https://rightcheckin.com/blog/the-guide-to-spirit-airlines-seat-selection-unlocked/
