Traveling with pets in-cabin is only allowed for cats and dogs when there's space available. Each customer can travel with up to two pets. If you're traveling with two pets, you must purchase two seats on your flight. Your second seat needs to be next to your assigned seat so you can care for both pets.

Generally, airlines charge a pet fee of $100 to $200 each way, but prices will vary depending on where you're traveling and your airline. Check the airline's pet policy before purchasing a ticket to make sure your pet meets the airline's breed and size requirements. If not, the airline won't let them board.
