Airline Kennel for Dogs: Fees, Dimensions, and Requirements
Most airlines require dogs to travel in an IATA-compliant kennel that allows the animal to stand, turn around, and lie down. Hard-sided plastic kennels with metal mesh doors are standard for cargo transport, while soft-sided carriers fit under seats for cabin travel. Airlines such as Delta Cargo and United Pets publish updated kennel size charts and fee tables online, with fees typically ranging from $125 to $200 each way for domestic U.S. flights. The International Air Transport Association (IATA) sets the Live Animals Regulations that govern kennel ventilation, labeling, and absorbent bedding requirements. For the latest fee schedule and kennel dimensions, see the Delta Cargo live animal shipping page Delta Cargo Pet Transport.
Fees vary by carrier, route, and kennel size. American Airlines charges a $200 fee for pets in cargo on most domestic routes, while Alaska Airlines charges $125 for in-cabin pets and $200 for checked pets. The kennel must have a secure locking mechanism, water containers, and a "Live Animal" label with arrows indicating upright positioning. Airlines may refuse certain breeds, such as snub-nosed dogs, due to respiratory risks at altitude. The U.S. Department of Transportation enforces the Air Carrier Access Act and tracks pet incident reports, which are available on the DOT website DOT Pet Travel.

United Airlines operates the largest pet cargo program in the U.S. through United Pets, handling over 100,000 animals annually and offering temperature-controlled holds. Delta Cargo maintains a dedicated Live Animals desk and operates pet relief areas at major hubs including JFK, LAX, and ATL.

Lufthansa Cargo and KLM Cargo are leading European options for international pet transport, both adhering to IATA standards and offering real-time tracking for live animal shipments Lufthansa Cargo Live Animals.
Rankings of pet-friendly airlines change based on incident reports and policy updates. The DOT publishes an annual Air Travel Consumer Report that includes data on pet incidents, denied boarding, and mishandled baggage for dogs in kennels. In 2024, Delta and United reported the highest number of pet shipments, while Alaska Airlines consistently ranks high for in-cabin pet satisfaction due to its straightforward fee structure and no-breed restrictions for most dogs. For current incident data and carrier performance, see the DOT Air Travel Consumer Report DOT Air Travel Reports.
How to Book and Prepare Your Dog's Kennel for Air Travel
Booking a pet kennel reservation typically requires contacting the airline's cargo or pet desk directly, as most carriers do not allow pet reservations through standard online booking flows. You must provide the kennel dimensions, dog weight, breed, and health certificate issued by a USDA-accredited veterinarian within 10 days of travel. Airlines require a current rabies vaccination certificate and a health certificate for international flights, with some countries requiring additional import permits and microchip identification USDA Pet Travel.
Preparation steps include acclimating the dog to the kennel at least two weeks
