Southwest Airlines Pet Carrier Policy – Size, Rules &

The southwest airlines pet carrier policy explains the requirements for bringing pets onboard. Southwest allows small pets to travel in the cabin if they are placed inside an approved carrier that fits under the seat. The carrier must be leak-proof, well-ventilated, and meet the size limit specified by the airline. Passengers must pay a pet fee per flight direction, and only a limited number of pet carriers are allowed on each flight, so booking early is recommended. Additionally, pets must remain inside the carrier throughout the journey, and seating restrictions apply to ensure safety and comfort. Reviewing the carrier policy in advance helps avoid delays or denied boarding at the airport.
