Spirit Airlines baggage allowance summary

Use this quick guide to compare your bag against Spirit Airlines's published cabin bag and personal item limits. The WillitFit checker is designed to help travellers spot oversize bags before they reach the gate.

Personal item size: 45 × 35 × 20 cm; Usually stored under the seat in front.

Before you pack

Measure the packed bag, not the empty manufacturer size. Bulging pockets, handles and wheels can affect whether the bag fits the sizer.

At the airport

Keep documents, liquids and electronics easy to reach so you do not need to open and repack your bag during security or boarding.

If your bag is close

A close result means there may be little tolerance. Use the checker, reduce soft contents where possible, and confirm the latest rules with the airline.
