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 Southwest Airlines?
Southwest Airlines publishes 60 x 40 x 25 cm for the cabin bag, 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.

Underseat item
Southwest Airlines publishes Check fare conditions 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. The weight allowance changes with fare type, so check your ticket.
dimensions
Overhead cabin bag
Southwest Airlines publishes 60 x 40 x 25 cm as the physical carry-on limit; it goes in the overhead bin. This describes size and storage only, not ticket entitlement. Southwest Airlines does not publish a weight limit for this bag — the size frame is what gets enforced.

context
Airline context
Southwest 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.

No. CabinFit compares your measurements with the limits Southwest Airlines published (Southwest optional travel charges, last checked Aug 9, 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 Southwest Airlines's cabin policies for pets, instruments, or sports equipment yet, and it will not invent them. Use the official Southwest Airlines baggage page linked above for those rules.
