For many pet owners, the idea of placing their furry companion in a carrier and sending them into the cargo hold is not comforting. Traveling with pets, especially on international flights, can be stressful and complicated. Concerns about safety and separation often add to the anxiety. Fortunately, several pet-friendly airlines allow small pets, within specific size and weight limits, to travel in the cabin with their owners. This is a safer and more comfortable option for both pets and their humans.
With an increasing number of airlines offering in-cabin pet travel, we have compiled a helpful list to guide your search. Each airline sets its own rules regarding the number of pets allowed in the cabin and the approved pet carrier dimensions. It is important to research carefully or work with a pet relocation company to find the airline that meets your needs and ensures a smooth journey for your pet.
1. American Airlines
American Airlines remains one of the top pet-friendly airlines in the U.S., allowing small cats and dogs to travel in the cabin on select flights. Pets must remain in an approved soft- or hard-sided carrier that fits under the seat in front of you. The maximum carrier dimensions are 18” x 11” x 11” inches for soft-sided and 19” x 13” x 9” inches for hard-sided carriers. While there is no official combined weight limit listed in their current policy, pets must be small enough to move comfortably within the carrier and remain fully enclosed at all times. Only one pet carrier is allowed per passenger, and space is limited to 7 in-cabin pets per flight, booked on a first-come, first-served basis. Pets are not permitted in First or Business class on certain aircraft due to space restrictions. The pet fee ranges from $125- $200 each way for flights. For travelers asking which airlines allow pets in the cabin, American Airlines for pet is a consistent and accessible choice for U.S. and select international routes.
2. Air Canada
Air Canada is a reliable choice for travelers seeking flights that allow pets in the cabin. The airline permits small dogs and cats to travel in the cabin as long as they remain in a soft-sided carrier that fits under the seat in front of you. Effective June 1, 2025, only soft-sided carriers are accepted, and hard-sided ones are no longer allowed. While Air Canada does not specify a strict weight limit, most guidelines suggest that the combined weight of the pet and carrier should be under 22 pounds, and pets must be able to stand, turn around, and lie down comfortably inside the carrier. Only one pet per passenger is allowed, and the pet counts as your carry-on item. Pets are not permitted in bulkhead or exit rows, and cannot be brought into Premium Economy or Business Class cabins. Unaccompanied minors may not travel with pets. The pet-in-cabin fee ranges from CAD/USD 50–60 for domestic or U.S. flights, and CAD/USD 100–120 for international travel. With clear pet travel policies and a broad global network, Air Canada continues to be one of the most pet-friendly international airlines available.
3. Air France
Air France allows small dogs and cats to travel in the cabin on most flights, provided the combined weight of the pet and a soft-sided carrier does not exceed 17.64 lb (8 kg). Carriers must be soft-sided, measure no more than 18″ × 11″ × 9″ (46 × 28 × 24 cm), and the pet must be able to stand, turn, and lie down comfortably. Hard crates are not allowed in the cabin.
