Spirit Airlines uses a boarding zone system to organize how passengers get on the plane. Zones are assigned based on things like ticket type, seat selection, and add-ons like Shortcut Boarding. Passengers who need extra time, such as those with disabilities or small children, are allowed to board first. After that, priority passengers and then standard ticket holders are called by zone. Knowing your boarding group can help you plan ahead and find overhead space more easily. It’s a simple system that helps keep boarding smooth and stress-free.
