Spirit Airlines Boarding Zones system to ensure a smoother and more organized process at the gate. Passengers are assigned a boarding zone, which is clearly indicated on their boarding pass. Zone 1 is for priority passengers, such as those with special needs, or those who have purchased upgrades like Big Front Seats or Fast Track Boarding. Zone 2 is for passengers who have purchased Bundle It packages, offering a mix of benefits including priority boarding. Zone 3 is typically for passengers with $9 Club memberships or other selected services. Zones 4 and 5 are for regular passengers, with Zone 5 being the last group to board. This system helps manage the flow of passengers, reduce gate congestion, and ensure that everyone has enough space for their carry-on bags. By understanding your assigned boarding zone, you can plan your arrival time at the gate and avoid unnecessary stress during the boarding process.
