Where Southwest Airlines flies from
The airports Southwest Airlines operates the most scheduled nonstop departures from.
Southwest Airlines baggage allowance
Allowances on a low-cost carrier are unbundled — the fare buys the seat and almost nothing else, so what you can bring depends entirely on which fare or bundle you selected at booking.
Expect a small personal item that fits under the seat to be included, and everything larger — a full-size cabin bag, any checked bag, and often seat selection — to be a paid add-on. Cabin bag size limits are measured and enforced at the gate far more strictly than on full-service airlines, and paying for a bag at the airport typically costs several times the online price.
Check the fare conditions on your own booking confirmation before you pack: two passengers on the same flight can have completely different allowances.
Southwest Airlines cabins
Southwest Airlines operates a single-class cabin. There is no business or premium cabin to upgrade into — the paid options are extra legroom seats, priority boarding and baggage bundles, all bought as add-ons rather than as a separate class of travel.

Southwest Airlines operates Boeing 737-700, Boeing 737-700 With Winglets, Boeing 737-300, Boeing 737-500, Boeing 737-800 With Winglets on the routes in our data. Aircraft type varies by route and by day, and airlines swap equipment at short notice, so treat this as the typical fleet on this network rather than a guarantee for your flight.
