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. On low-cost fares, size checks are part of the business model, so a bag within 1 cm of any limit is a gamble. Hard shells can't squeeze and soft bags bulge once packed — leave yourself a margin.

Underseat item
Southwest Airlines publishes Check fare conditions for the personal item on Standard carryon allowance, but whether it's included depends on your ticket, and it has to fit under the seat in front of you. The weight allowance changes with fare type, so check your ticket.

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.
