Safest Airlines That Ship Pets Alone in 2026: Full Comparison

Delta Airlines and American Airlines are the two major U.S. carriers that currently ship pets unaccompanied in cargo. United Airlines suspended its PetSafe cargo program in 2018 and no longer accepts unaccompanied pets. All airlines that accept pets in cargo require an airline-approved crate, a health certificate issued within 10 days of travel, and proof of rabies vaccination. Pets cannot fly when ground temperatures exceed 85°F or drop below 45°F.

If you need to send your pet on a flight without you — whether because of a military move, a long-distance purchase from a breeder, or a relocation — knowing which airlines are safest and what the current rules are can save you time, money, and stress. Below is a complete comparison of airline pet cargo programs in 2026, plus a ground transport alternative that many pet owners find safer.

Safest Airlines that Ship Pets Alone

Following reports of pet mistreatment on some airlines, many pet owners are looking for safer ways to transport their furry friends.

If you are looking for an airline to ship your pet solo, there are a few options that you should consider.

Delta Air Lines Pet Shipping

As of 2026, Delta’s pet transportation policies have become significantly more restrictive. For most travelers, Delta allows only small dogs and cats to travel in the cabin with a ticketed passenger. Delta’s cargo pet-shipping program is currently limited primarily to active U.S. military members and certain government personnel traveling under official relocation orders. Large pets that cannot fit under the seat generally cannot be shipped through Delta by the average traveler.

For in-cabin travel, pets must fit comfortably inside an airline-approved carrier that can be stowed beneath the seat. Delta currently charges approximately $150 each way on domestic routes and $200 each way on most international routes for in-cabin pets.

Delta prohibits many brachycephalic (snub-nosed) breeds from cargo transport due to increased respiratory risks. Restricted breeds include dogs such as Pugs, Bulldogs, Boston Terriers, and similar mixes, as well as Persian, Himalayan, and other snub-nosed cat breeds.

When cargo transport is permitted, Delta requires IATA-compliant kennels large enough for the animal to stand, turn around, sit upright, and lie down naturally. Combined kennel and pet weight limits vary by aircraft type, with some aircraft allowing up to 100 pounds combined. Weather embargoes also apply when temperatures exceed approximately 80°F or fall below 20°F during any portion of the trip.

United Airlines Pet Shipping

United Airlines no longer offers unaccompanied pet cargo transportation for the general public.

United’s former PetSafe cargo program was suspended in 2018 following multiple pet-related incidents and has never returned as a standard service for most customers. As of 2026, United allows small dogs and cats to travel only in the cabin with a ticketed passenger, provided the pet remains inside an approved carrier that fits beneath the seat.

This distinction is important because many pet owners searching for “United Airlines pet cargo” assume the airline still ships pets independently. In reality, if your pet cannot travel with an accompanying passenger, United generally does not offer a cargo solution.

For pet owners who need unaccompanied transport, the most common alternatives are:

• Hiring a flight nanny to accompany the pet in the cabin
• Using a professional ground pet transport service
• Traveling personally with the pet as an in-cabin passenger

Ground transportation is often the preferred option for larger dogs, brachycephalic breeds, senior pets, and animals that may not qualify for airline travel. It also avoids many airline restrictions related to temperature embargoes, aircraft limitations, and carrier size requirements. If your pet is small enough to fly in the cabin, check United’s current in-cabin pet rules before booking. Policies, fees, and route restrictions can change frequently.

American Airlines Pet Shipping (PetEmbark® Program)

American Airlines currently handles larger pet transportation through American PetEmbark®, a cargo-based service operated through American Airlines Cargo for pets that cannot travel in the cabin. Pets that meet size requirements may still travel under the seat with an accompanying passenger on eligible routes.

PetEmbark requires pets to travel in USDA- and IATA-compliant kennels that are large enough for the animal to stand, sit, turn around, and lie down comfortably. For many routes, the combined weight of the pet and kennel cannot exceed approximately 100 pounds (45 kg). Kennels must be securely fastened with metal hardware and meet American Airlines Cargo specifications.

American Airlines restricts many snub-nosed (brachycephalic) breeds from cargo transportation because of elevated breathing risks. This commonly affects breeds such as:

• Bulldogs
• French Bulldogs
• Pugs
• Boston Terriers
• Persian cats
• Himalayan cats
• Similar brachycephalic mixes

Seasonal weather restrictions also apply. Pets may be embargoed during periods of extreme heat or cold, particularly on routes where animals would be exposed to outdoor temperatures during loading, unloading, or transfers.

Pricing varies significantly based on route, animal size, kennel dimensions, destination, and whether specialized handling is required. Typical PetEmbark shipments often fall in the $200–$500+ range for shorter domestic routes, while larger pets, longer routes, and international shipments can cost substantially more. Because pricing is quote-based, owners should request a specific estimate before making travel plans.

For many pet owners, especially those transporting puppies, kittens, senior pets, or snub-nosed breeds, professional ground transportation remains a popular alternative because it avoids airline breed restrictions, cargo limitations, and seasonal embargoes while providing continuous supervision throughout the trip.

Airline Pet Cargo Safety Comparison Table

Not all airlines handle pet transportation the same way. Some allow cargo transport, while others only permit pets in the cabin when accompanied by a passenger. Before booking, compare airline restrictions, costs, and cargo availability.

*Policies change frequently. Always verify current airline requirements before booking.

Because airline rules can change seasonally, many pet owners compare airline options against professional ground transport, especially for larger dogs, senior pets, and snub-nosed breeds.

Temperature and Breed Restrictions by Airline

Temperature restrictions are one of the most common reasons pets are denied airline travel. Most airlines will not transport pets if forecast temperatures at the origin, destination, or connecting airport fall below approximately 20°F (-7°C) or exceed 80–85°F (27–29°C). Many airlines also enforce restrictions on brachycephalic (snub-nosed) breeds because these animals face increased respiratory risks during air travel.

Commonly restricted dog breeds include:

• French Bulldogs
• English Bulldogs
• American Bulldogs
• Pugs
• Boston Terriers
• Boxers
• Shih Tzus
• Pekingese

Commonly restricted cat breeds include:

• Persian Cats
• Himalayan Cats
• Burmese Cats
• Exotic Shorthairs

Seasonal embargoes are especially common during summer months in southern states such as Texas, Florida, Arizona, Nevada, and parts of California. Airlines may suspend pet cargo service entirely during periods of extreme heat.

Because breed restrictions and weather embargoes vary by carrier and route, owners of brachycephalic breeds often choose professional ground transportation instead. Ground transport avoids many airline limitations while allowing pets to travel in climate-controlled vehicles with regular monitoring, food, water, and exercise breaks.

What Documents Do You Need to Ship a Pet by Air?

Most airlines require several documents before a pet can travel by air. Requirements vary by airline and destination, but the following paperwork is commonly required:

Certificate of Veterinary Inspection (Health Certificate)

A health certificate issued by a licensed veterinarian is required for most airline pet travel. For domestic flights, airlines commonly require the certificate to be issued within 10 days of travel. The veterinarian confirms that the pet is healthy and fit to fly.

Rabies Vaccination Records

Most destinations require proof of current rabies vaccination. Puppies and kittens may be exempt if they are below the minimum vaccination age, but destination-specific rules still apply.

USDA-APHIS Endorsement

For many international destinations, the health certificate must be endorsed by the USDA Animal and Plant Health Inspection Service (APHIS) after your veterinarian completes the examination.

Airline-Specific Forms

Some airlines require additional cargo booking paperwork, acclimation certificates, import permits, or liability forms depending on the route and destination country.

Pet owners traveling internationally should also review current requirements from the Centers for Disease Control and Prevention and destination-country authorities before booking flights. Requirements can change frequently, particularly for dogs entering the United States.

How Much Does It Cost to Ship a Pet on an Airline?

The cost of airline pet transportation depends on the airline, route, destination, pet size, and travel method.

In-Cabin Pet Fees

Small pets that fit beneath the seat typically incur airline pet fees ranging from $95 to $200 each way. These fees are paid in addition to the passenger’s ticket.

Cargo Pet Shipping

For pets traveling through airline cargo programs, costs typically range from $200 to $1,000+. Large dogs, oversized kennels, international routes, and multi-leg itineraries can significantly increase pricing.

Flight Nanny Services

If you cannot accompany your pet but want it to travel in the cabin, a flight nanny may be an option. Flight nanny services generally cost $300–$500+ for the escort’s fee, plus airfare and airline pet fees. Total costs often range from $500 to $1,500+ depending on the route.

Ground Transport Alternative

Professional ground transport is often competitively priced with airline travel, especially for larger pets that cannot travel in-cabin. Costs vary by distance and route, but many pet owners choose ground transportation because it avoids airline breed restrictions, temperature embargoes, cargo handling concerns, and airport transfers.

When comparing costs, remember to include additional expenses such as health certificates, travel crates, airport transportation, and overnight accommodations if required. For many long-distance moves, the total cost difference between airline transport and professional ground transport is smaller than owners initially expect.

How to Ensure Your Pet’s Safety for Air Travel

In addition to choosing the right airline, there are a few other things you can do to ensure your pet’s safety while traveling by air. Here are a few tips:

#1. Check airline policies: Ensure you are familiar with the airline’s pet policies before booking your ticket. 

#2. Have your pet examined by a vet before travel: It’s a good idea to have your pet examined by a vet before traveling. This will help ensure your pet is healthy and fit to travel. 

#3. Get an airline-approved carrier: Make sure your pet carrier meets the size and weight requirements of the airline. The crate should be large enough for your pet to stand and turn around in, and it should also be well-ventilated.

Conclusion

Traveling with a pet can be stressful, more so when you need to get them on the plane without you.  But if you choose the right airline and follow the safety tips mentioned above, you can rest assured that your pet will have a safe and comfortable journey.
