Southwest Airlines makes it easy for pet lovers to travel with their small dogs or cats. Pets are welcome in the cabin as long as they stay inside an approved pet carrier that fits under the seat in front of you. The airline requires the carrier to be secure, breathable, and cozy enough for your pet to move comfortably. Your pet must remain in the carrier at all times during the flight and while at the airport. The Southwest Airlines carry on pet policy helps ensure a safe and stress-free experience for both you and your animal companion. |
