Southwest Airlines Carry On Pet Policy

Under Southwest Airlines’ carry-on pet policy, small, vaccinated dogs and cats are allowed to travel in the cabin with an approved pet carrier that fits under the seat. Because of the flight’s pet limit, passengers must make reservation in advance. Pets must be well-behaved, not more than eight weeks, and not accepted on flights to Hawaii or other countries. Pets are not allowed in exit rows and seats without under-seat storage, which guarantees a comfortable and safe journey. There is a fee related to this.
