Flying a dog on a domestic U.S. flight costs $200 to $600 when the dog flies in the cabin. Airline in-cabin pet fees run from $99 (Frontier) to $150 (United) each way. Dogs too large for the cabin must fly as cargo, which now runs $500 to $1,000+ each way after United killed its PetSafe program and Delta suspended pets-as-checked-baggage. Add a soft-sided carrier ($25–$75) or an IATA hard-shell crate ($100–$200), a vet health certificate ($50–$300), and a flight nanny ($300–$700+) if you can’t travel with the dog yourself.
Below is the full breakdown: 2026 airline pet fees, the extra costs that catch most owners off guard, what flying a large dog actually runs now that United and Delta have pulled back on cargo, what international shipping costs, and when ground transport makes more sense than flying.
Domestic Flight Fees for Dogs
There are three ways to transport a dog by air: shipping them as cargo, traveling with them in the cabin, or checking them as baggage in the cargo hold. Each airline sets its own size, weight, breed, and seasonal rules, so always confirm policy on the airline’s site before booking.
#1. Cost of Flying a Dog on American Airlines
American Airlines charges a $150 in-cabin pet fee per kennel. The pet and carrier combined must weigh no more than 20 pounds, and the carrier must fit under the seat in front of you. If you travel with multiple pets in one kennel, you pay one fee, but the combined weight still has to meet the airline’s threshold.
Larger dogs cannot travel in the cabin. American Airlines moves them via American Airlines Cargo, with fees of $500 to $1,000+ depending on weight and route. This is a cargo shipment, not checked baggage — American does not currently allow pets to be checked as luggage.
#2. Cost of Flying a Dog on Southwest Airlines
On Southwest Airlines, the dog ticket price is $125 per pet carrier each way on domestic flights. You can bring one personal item in addition to the carrier. The carrier must fit under the seat in front of you and your dog must be able to stand up and turn around comfortably inside. Southwest does not allow pets as checked baggage or as cargo.
#3. Cost of Flying a Dog on Delta Air Lines
Delta charges $150 each way for in-cabin pets on domestic flights within the United States, Canada, and Puerto Rico. International in-cabin travel runs $200 or more each way. Delta has suspended its checked-baggage pet service, so large dogs cannot fly with Delta unless arranged through cargo on select routes. Confirm the latest policy at booking.
#4. Cost of Flying a Dog on United Airlines
United Airlines allows cats and dogs in the cabin for $150 each way. If you have a domestic layover longer than four hours, or an international layover longer than 24 hours, you pay an additional $125 fee. Travel credits cannot be used for the pet fee. United caps in-cabin pets at two per flight, each in an approved carrier. The pet and carrier combined must not exceed 20 pounds. United discontinued its PetSafe cargo service after the COVID pandemic, which means United no longer transports large dogs as cargo at all.
#5. Cost of Flying a Dog on Frontier Airlines
Frontier Airlines charges $149 to $150 each way for in-cabin pets, the lowest standard fee among major U.S. carriers. Service animals fly free with the required documentation. Frontier does not transport pets in the cargo hold.
#6. Cost of Flying a Dog on Alaska Airlines
Alaska Airlines accepts cats, dogs, ferrets, guinea pigs, hamsters, and household birds. The fee is $100 each way in the cabin and $200 each way in the cargo hold for domestic flights.
Specific rules apply:
- The combined weight of the pet and carrier must be no more than 150 lbs.
- You must travel on the same flight(s) as your pet to its destination.
- Dogs and cats must be at least eight weeks old and weaned.
- A vet-issued health certificate is required for each pet traveling in the baggage compartment.
- At most one live dog or cat (six months or older) may travel in a single carrier.
- All animals must be calm, non-destructive, and require no attention during transit.
Alaska is one of the few remaining U.S. airlines that allows you to check a dog in the baggage compartment on select routes. Availability is limited and strict crate, weather, and breed conditions apply.
Additional Costs of Flying a Dog
The airline pet fee is only part of the total. Several other expenses can change the math significantly.
#1. Surcharges and Hidden Fees
Airlines may add surcharges for layovers, oversize crates, summer/winter route restrictions, or destination-specific paperwork. These can range from $50 to $500+. Read your selected airline’s pet policy in full before paying.
#2. Airline-Approved Pet Carriers
Carrier costs depend on the type:
- Soft-sided in-cabin carrier: $25–$75. Must be ventilated, fit under the seat, and let the dog stand up and turn around.
- IATA-compliant hard-shell cargo crate: $100–$200. Required for any dog traveling in the cargo hold.
If your dog flies as cargo, the crate must meet IATA Live Animal Regulations:
- Large enough for the dog to stand up and turn around without touching the top.
- Secure locks with pins that extend past the extrusions above and below the door.
- Ventilation on all four sides.
- Externally visible name and contact information label.
- Food and water bowls attached to the door and accessible from outside the crate.
- Assembled with metal hardware, not plastic fasteners that can come loose in transit.
An inadequate crate is one of the most common reasons airlines cancel a pet booking at check-in.
#3. Veterinary Health Certificate
A veterinary health certificate (Certificate of Veterinary Inspection, or CVI) costs $50–$300 depending on your vet, your location, and whether extra tests or vaccinations are needed. Most airlines require the certificate be issued within 10 days of travel; some allow up to 30 days for domestic trips.
Some U.S. states and most international destinations have additional entry requirements: import permits, extra vaccinations, or USDA endorsements. Schedule your vet appointment close to your departure date and confirm requirements with both the airline and the destination well in advance.
How Much Does It Cost to Fly a Large Dog?
Most major airlines only allow dogs under about 20 pounds in the cabin. Larger dogs must fly as cargo (when available), and 2026 cargo fees commonly run $500 to $1,000+ each way. Several airlines have stopped offering pet cargo programs altogether: United discontinued PetSafe and Delta suspended checked-baggage pets, which means American Airlines Cargo and Alaska Airlines are now the practical options for most domestic large-dog routes.
Combined with the IATA crate ($100–$200), vet paperwork ($50–$300), and your own airline ticket, the total cost of flying a large dog domestically can easily exceed $1,000–$2,000.
Most large-dog owners now skip the cargo hold entirely. Booking ground transport through CitizenShipper sidesteps breed bans and seasonal temperature embargoes, and your dog rides in a climate-controlled vehicle with regular bathroom and exercise stops.
How Much Does It Cost to Fly a Small Dog in Cabin?
Flying a small dog in the cabin is the most affordable air option. Pet fees range from $95 to $150 each way depending on the airline, plus a $25–$75 soft-sided carrier. Total one-way out-of-pocket cost is typically $150–$300 once the carrier is included.
Most airlines require the dog and carrier combined to weigh under 15–20 pounds. The carrier must fit under the seat in front of you, and the dog must remain inside the carrier for the entire flight — it cannot sit on your lap. Airlines also cap how many pets are allowed in the cabin per flight, so book the pet reservation as early as you book your own seat.
Puppy Age Requirements for Flying
Most U.S. airlines require puppies to be at least 8 weeks old and fully weaned before flying. For international or some interstate travel, airlines require puppies to be at least 16 weeks old so they can complete a rabies vaccination on the standard schedule.
Always confirm the airline’s age rule and the destination’s import requirements before booking — they don’t always match.
Brachycephalic Breed Restrictions
Most airlines restrict or outright ban brachycephalic (flat-faced) breeds like Bulldogs, Pugs, Boston Terriers, Boxers, and Shih Tzus from cargo travel, because their shortened airways make them more prone to respiratory distress at altitude and in temperature swings. United, Delta, and American have particularly strict limits. Even when these breeds are allowed in the cabin, the airline may ask for extra paperwork or a vet sign-off at check-in.
For a flat-faced breed on a long-distance move, ground transport is almost always the safer bet.
Practical Tips for Flying with Your Dog
A handful of small decisions can lower your costs and make the trip safer for your dog:
- Fly off-season when airports are less crowded and pet bookings are easier to secure.
- Watch the weather — airlines cancel pet tickets when ground or cargo temperatures fall outside the 45°F to 85°F range.
- Book direct flights with no layovers, especially for cargo travel.
- Freeze water in a crate-attached bowl before the flight so it melts gradually and does not spill on the runway.
- Arrive at least 2.5 hours early for a domestic flight to handle pet check-in without rushing.
- Do not hand your dog over to airline staff until 30 minutes before departure to minimize time on the tarmac.
- For cargo travel, watch ground crew load your dog before you board the aircraft.
- Keep a recent photo of your dog with you in case you get separated at arrival.
- Do not sedate your dog. Sedation interferes with temperature regulation and balance during turbulence — most airlines will refuse the pet at check-in if sedation is suspected.
- Use a quality crate that is the right size. Too small means refusal; too large means the dog gets thrown around.
- Carry vet certificates, vaccination records, and any import paperwork in a single easy-access folder.
- Put your contact information on both the crate and the dog’s collar.
How Much Does It Cost to Fly a Dog Internationally?
International dog transport costs a lot more than a domestic flight. Total budgets typically land between $1,000 and $5,000+ depending on the destination, airline, dog size, and import rules.
Expect line items for:
- International airline cargo fees
- Veterinary exam and certification
- USDA endorsement of paperwork (starting around $38)
- Destination import permits
- Customs clearance
- IATA travel kennel
- Quarantine expenses, if the destination requires them
Strict rabies-control destinations like Australia, New Zealand, Japan, and Hawaii can require months of advance planning, blood titer tests, and quarantine on arrival. For these destinations, start the process at least 6 months before you travel.
Country-specific rules change frequently, so many owners hire an international pet relocation company to manage the paperwork.
Dog-Only Airlines and Charter Flights
A small but growing set of operators now run dog-friendly flights that skip traditional airline cargo entirely. The most established names:
- BARK Air. Passenger seats for dogs next to their owners on a handful of U.S. and international routes. Per-dog tickets typically start in the low thousands.
- K9 Jets. Shared private-jet flights designed around dogs, with U.S., U.K., and European routes.
- RetrievAir. Newer entrant focused on pet-only charter service.
Shared seats commonly start at several thousand dollars per pet, so these flights are not cheap. They tend to make sense for large dogs, brachycephalic breeds, anxious pets, show dogs, and high-value breeding animals where traditional cargo is too risky.
Flight Nanny Service
A flight nanny is a person you hire to fly with your dog when you cannot travel yourself. The nanny books their own round-trip ticket and brings the dog as their in-cabin pet (or as cargo on the same flight). Because the dog rides with a human, some airlines waive separate pet handling fees, which can offset part of the nanny’s cost.
Typical flight nanny fees run $600+ domestic and more than $2000 on top of the nanny’s flight cost, depending on distance, dog size, and the number of pets traveling. Nannies became more common after a TikTok video showcasing the job went viral in 2022, and the market has steadily grown since.
How to Find a Pet Transporter to Fly Your Dog
If you need a vetted third-party transporter, the International Pet and Animal Transportation Association (IPATA) publishes a directory of member transporters who agree to its standards of care. IPATA members handle both air and ground transport and can manage international paperwork on your behalf.
For domestic ground transport, you can post your route on CitizenShipper and receive quotes from independent, background-checked drivers within minutes.
The 2026 CDC Rule for Flying Dogs Into the U.S.
The CDC’s updated rules restrict bringing dogs into the U.S. from countries the CDC classifies as “high risk” for rabies, or any dog that has been in a high-risk country in the past six months. American Airlines and other carriers have embargoed dogs originating from these countries. If you are returning to the U.S. with a dog after travel abroad, confirm the CDC’s current high-risk country list before booking.
When Ground Transport May Be a Better Fit
If you have a large dog, a flat-faced breed, or a dog that panics in crates, ground transport is usually cheaper than cargo and the dog never enters a cargo hold. The same is true for any move long enough that you’d otherwise have to fly the dog separately from you.
CitizenShipper is a marketplace where independent drivers across the U.S. bid on your transport route. A few specifics:
- Every driver is background-checked and many are USDA-registered before they’re allowed to quote.
- Every booking includes a $1,000 pet protection guarantee.
- You get 24/7 TeleVet access through Vetster for the whole trip.
- Because drivers bid against each other, quotes typically come in 60–70% below traditional pet shippers.
- The quote you accept is the price you pay. No surprise fees at pickup or drop-off.
Post your dog’s transport details and you’ll start receiving driver quotes within minutes. Get free dog transport quotes and compare drivers side by side before you book.
