Fare type notes
Some airlines include only a smaller underseat item with basic fares. Larger cabin bags can require a paid bundle, priority service, or eligible ticket.
How strict is Spirit Airlines?
Spirit Airlines publishes 45 x 35 x 20 cm for the personal item, and at the gate the sizer frame decides — not your tape measure. CabinFit does not publish an enforcement score; a bag within 1 cm of any limit leaves almost no packing margin. Hard shells can't squeeze and soft bags bulge once packed — leave yourself a margin.

dimensions
Underseat item
Spirit Airlines publishes 45 x 35 x 20 cm as the physical personal item limit; it has to fit under the seat in front of you. This describes size and storage only, not ticket entitlement. Spirit Airlines does not publish a weight limit for this bag — the size frame is what gets enforced.

Overhead cabin bag
Spirit Airlines does not have a verified carry-on size in our catalogue yet, so confirm the limit with the operating carrier before bringing an overhead bag.

context
Airline context
Spirit Airlines is a low-cost carrier based in United States. Like most low-cost carriers, the free allowance is usually just the underseat bag — the larger cabin bag is often a paid add-on, so match your bag to your exact fare before you get to the gate.

Spirit Airlines publishes 45 x 35 x 20 cm as the physical size limit. This does not confirm ticket entitlement; check whether the bag is included with your fare.
The current CabinFit data does not include a separate carry-on dimension for Spirit Airlines. Check your ticket and the official baggage page.
No. CabinFit compares your measurements with the limits Spirit Airlines published (Spirit customer support, last checked Aug 10, 2026). Gate staff, fare conditions, and aircraft changes can still affect the final decision — keep a margin and open the official page before you fly.
CabinFit has not verified Spirit Airlines's cabin policies for pets, instruments, or sports equipment yet, and it will not invent them. Use the official Spirit Airlines baggage page linked above for those rules.
