The Southwest Airlines Pet Policy provides clear guidelines for travelers wishing to bring their small pets along on domestic flights. Only small, vaccinated cats and dogs are permitted, and they must be transported in a well-ventilated, leak-proof carrier that fits under the seat. Each customer is allowed one pet carrier, which can house up to two pets of the same species. A pet fare is required, and availability is limited, so early booking is recommended. Pets are not allowed on international flights or as checked baggage. By following the Southwest Airlines Pet Policy, passengers can ensure a safe and comfortable journey for both themselves and their furry companions.
