Before taking off with your furry friend, it’s important to understand the southwest airlines pet policy and what it requires from passengers. Southwest allows vaccinated small cats and dogs to fly in the cabin, provided they remain inside an airline-approved carrier that fits under the seat. Travelers must pay a $95 pet fare per direction, with all bookings handled on a first-come, first-served basis due to the six-pet limit per flight. This detailed guide explains age requirements, seating restrictions, destination limitations, and important dos and don’ts of pet travel with Southwest. With the right preparation, flying with your pet becomes a comfortable and seamless experience.
