Southwest Pet Policy in Cabin: Rules for Flying with Pets
The southwest pet policy in cabin explains how passengers can travel with small pets safely and comfortably. Southwest Airlines allows only vaccinated cats and dogs that are at least eight weeks old to fly in the cabin on domestic routes. Pets must remain inside an airline-approved, leak-proof carrier that fits under the seat in front of you at all times. Each traveler is permitted only one pet carrier, and space is limited per flight. Since pet spots are available on a first-come, first-served basis, planning ahead is essential to ensure your pet can travel with you.
