Southwest Airlines is known as one of the few airlines with a generous free baggage policy for all passengers. When planning to travel with checked baggage, Southwest is a good option compared to other "low-cost" airlines, as they allow 2 free checked bags on their flights. Other airlines may have a slightly lower base-fare, but end up costing much more when taking into account the price of checked bags.

Traveling With Pets: General Information
Southwest Airlines accepts small vaccinated domestic cats and dogs. All in-cabin pets must be carried in an appropriate carrier, as indicated below and are subject to a USD75 pet fare each way per pet carrier. The pet carrier counts as either a carryon item or a personal item.
Reservations for small cats and dogs can only be booked by calling Southwest Airlines at 1-800-I-FLY-SWA (1-800-435-9792). Pets will be accepted on a first-come, first-served basis until capacity is reached. The pet fare must be collected at the ticket counter, is nonrefundable, and may not be applied toward future-date travel if unused. Customers traveling with a cat or dog must check the pet in at the airport ticket counter and pay the pet fare before going to the departure gate. Customers can still secure their boarding pass online, at curbside checkin, the airport kiosk, or the ticket counter.
We maintain the right to refuse acceptance of a cat or dog exhibiting aggressive behavior or any other characteristics that appear incompatible with air travel.
Southwest Airlines does not accept pets (cats or dogs) traveling without a Customer.
Pets are not permitted to travel with Unaccompanied Minors.
Note: These requirements do not apply to assistance animals or emotional support animals accompanying a person with a disability.
Note: When passing through security, Customers will be asked to hold the pet and walk through the screening device while the carrier is x-rayed.
All pet carriers are subject to being searched by the Transportation Security Administration (TSA), other airport security authorities, as well as searches by airline personnel.
