Traveling With Pets: General Information
Southwest Airlines allows small vaccinated domestic cats and dogs to travel with you in-cabin under the seat in front of you. All pets must be carried in an appropriate carrier, as indicated below.
Animals are not allowed to travel in-cabin on international flights or any itinerary that includes an international flight.
Pets will be accepted on a first-come, first-served basis until capacity is reached. Six (6) pets are allowed per flight with a limit of one pet carrier per paying Customer traveling on the same flight. However, from time to time, circumstances may allow for more (or fewer) than six (6) pet carriers per scheduled flight.
Pets must be checked in at the airport ticket counter, however 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.
