If you're traveling with a pet on an American Airlines flight, you can contact their customer support at 1-844-987-7017 for assistance. American Airlines charges a fee of $125 each way for in-cabin pets. This applies to dogs, cats, and household birds, and your pet must be in an approved carrier that fits under the seat in front of you. Make sure to check the American Airlines pet policy for additional details about restrictions, such as the number of pets allowed per flight and breed restrictions. For help with your American Airlines reservation or booking, reach out to customer support. Pets traveling in the cabin must remain in their carriers at all times during the flight. Always contact American Airlines in advance to ensure all requirements are met for your pet's travel.
