Why some breeds face airline restrictions
If you own a bulldog, pug, boxer, Persian cat, or another flat-faced (brachycephalic) breed, you have probably already discovered that flying your pet is more complicated than it is for other breeds. Many airlines restrict or ban these breeds from cargo travel entirely.
The reason is anatomy. Brachycephalic animals have shortened skulls and compressed airways. Their breathing is already less efficient at rest, and the stress of air travel combined with temperature changes and altitude can make it dangerous. Airlines have experienced in-flight fatalities with these breeds, and most major carriers have responded by tightening their rules.
This does not mean your snub-nosed pet cannot travel. It means you need a different plan.
Which breeds are typically restricted
Dogs
The most commonly restricted dog breeds include:
- English Bulldog and French Bulldog
- Pug
- Boston Terrier
- Boxer
- Pekingese
- Shih Tzu
- Cavalier King Charles Spaniel
- Lhasa Apso
- Brussels Griffon
- Japanese Chin
- Mastiff breeds (English Mastiff, Bull Mastiff, Dogue de Bordeaux)
- American Bully and Staffordshire Bull Terrier (some airlines)
Mixed breeds with brachycephalic features may also be restricted. Airlines make the call based on physical characteristics, not just breed name.
Cats
Flat-faced cat breeds also face restrictions:
- Persian
- Himalayan
- Exotic Shorthair
- British Shorthair (some airlines)
- Scottish Fold (some airlines)
- Burmese
Airline-by-airline breakdown
Each airline sets its own rules. Here is a general overview of major US carriers as of 2026 (always verify directly before booking, as policies change):
Delta Air Lines: Does not accept brachycephalic breeds in cargo during summer months (typically May through September). Restrictions apply year-round for some breeds.
United Airlines: PetSafe cargo program has a restricted breed list. Snub-nosed breeds are accepted only during specific temperature windows.
American Airlines: Does not accept brachycephalic breeds in cargo at all, regardless of season.
Alaska Airlines: Accepts some brachycephalic breeds with additional conditions and temperature restrictions.
Southwest Airlines: Only allows small pets in-cabin (under seat). No cargo pet program.
JetBlue: Small pets in-cabin only. No cargo option.
International carriers vary widely. Some Asian and European airlines accept brachycephalic breeds in cargo with conditions. Others have full bans.
Options for shipping a restricted breed
In-cabin travel
If your pet is small enough to fly in-cabin (under 20 pounds including carrier, fits under the seat), the breed restriction usually does not apply. French Bulldogs and pugs frequently fly in-cabin without issue. This is the safest and simplest option when size allows.
Ground transport
For larger brachycephalic breeds that cannot fly cargo, ground transport is often the best choice. Professional pet transport services use climate-controlled vehicles with frequent rest stops. Domestic routes across the US typically cost $500 to $2,500 depending on distance.
Ground transport avoids the altitude, pressure changes, and confined cargo conditions that make air travel risky for flat-faced breeds.
Charter or pet-friendly airlines
A small number of pet-specific charter services and niche airlines cater specifically to pet travel, including brachycephalic breeds. These are more expensive but offer cabin-level conditions for your pet.
International moves: routing through accepting airlines
For international moves, we look for airlines that accept brachycephalic breeds on the specific route. Some carriers (particularly in Asia and the Middle East) are more flexible than US-based airlines. The route may need to be less direct, but it gets your pet there safely and legally.
Safety precautions for brachycephalic pets
If your flat-faced pet is cleared to fly, these steps reduce the risk:
- Travel during mild weather only. Avoid summer heat and extreme cold. Early morning or late evening flights are best.
- Use a crate one size larger than minimum requirements to give your pet extra airflow.
- Attach a water bowl and freeze it before departure so your pet has access to water without spillage.
- Do not sedate your pet. Sedation can further compromise breathing in brachycephalic breeds. Most vets and airlines advise against it.
- Get a pre-flight vet check specifically assessing respiratory fitness for travel.
- Avoid layovers when possible. Direct flights reduce total stress and time in transit.
How we handle brachycephalic breed moves
At Pet Travel Advisors, we coordinate moves for flat-faced breeds regularly. We know which airlines accept which breeds on which routes, and we monitor temperature and embargo windows to find safe travel dates. When cargo is not an option, we arrange ground transport or route through carriers that accept the breed.

Frequently asked questions
Can my French Bulldog fly at all?
Yes. If your French Bulldog is small enough for an in-cabin carrier (most are), you can fly together in the cabin on most airlines. Cargo is restricted on many airlines for French Bulldogs, but in-cabin travel is generally available.
Why do airlines ban certain breeds from cargo?
Brachycephalic breeds have compressed airways that make breathing harder under stress. The combination of altitude, temperature changes, and the stress of cargo travel has caused fatalities in these breeds. Airlines restrict them to reduce that risk.
Is ground transport safe for long distances?
Professional pet ground transport services use climate-controlled vehicles, make regular rest stops, and monitor pets throughout the trip. For brachycephalic breeds, ground transport is generally considered safer than cargo air travel for domestic moves.
My dog is a mix. Will the airline still restrict it?
Airlines evaluate physical characteristics, not just breed name. If your mixed-breed dog has a flat face and shortened snout, the airline may apply the brachycephalic restriction. When in doubt, contact us with a photo and we can advise on likely airline decisions.
Are there temperature restrictions on top of breed restrictions?
Yes. Most airlines that do accept brachycephalic breeds in cargo impose stricter temperature limits than for other breeds. Typical cutoff is 75 to 80 degrees Fahrenheit at origin, transit, and destination airports. Standard breeds may be allowed up to 85 degrees.
