Carry-On Pet Policy:
Southwest Airlines allows customers to carry small pets (cats and dogs only) on board all domestic Southwest Airlines flights. All in-cabin pets must be carried in an appropriate pet carrier. The pet fee is $95 each way per pet carrier. Each customer is limited to carrying one pet carrier on board. The carrier may contain up to two cats or dogs of the same species. The carrier will count as the customer’s carry-on bag. Southwest does not require a health certificate or any other documentation from the customer’s veterinarian for pets to travel. Pets are not permitted on international flights.
Checked Baggage/Cargo Policy:
Pets are not allowed in the cargo area on Southwest Airlines.
Soft-sided and hard-sided carriers specifically designed as pet carriers are acceptable. The carriers must be leak-proof and well ventilated. The pet carrier must be small enough to fit under the seat in front of the customer and be stowed in accordance with Federal Aviation Administration regulations. The cat or dog must be able to stand up and move around the carrier with ease.
Reservations for small cats or 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 total number of pet carriers per flight is limited at this time, so customers should make their pet reservations as soon as they confirm travel plans to ensure availability for their pets. The pet fee 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 in pets at the airport ticket counter and pay the pet fee before going to the departure gate. Customers can still secure their boarding pass online, at curbside check-in, the airport kiosk, or the ticket counter. Southwest Airlines does not accept pets traveling without a customer, and pets are not permitted to travel with unaccompanied minors or on international flights.
