Spirit Airlines Boarding Zones system to organize passengers during the boarding process. Passengers are assigned a zone number based on their ticket type, with higher-paying or elite status passengers typically boarding first. The zones are called out in order, starting from the front of the plane to the back. Spirit divides the zones into groups like Zone 1, Zone 2, and so on, and they usually begin boarding around 30 minutes before the flight's departure. To avoid confusion, it's a good idea to have your boarding pass ready to show the gate agent, as they will call passengers by zone number. Arriving early can also give you a better chance of getting in the earlier zones if you're interested in quicker boarding.
