American Airlines Animal Transport: How Pets, Service Dogs and Cargo Animals Fly in 2026

American Airlines animal transport covers how American Airlines moves live animals: small cats and dogs ride in the cabin for $150 per kennel each way, trained service dogs fly free, and most other pets travel as cargo through American Airlines Cargo's American PetEmbark service (American Airlines, 2026). Checked pets are accepted only for active-duty U.S. military and U.S. State Department Foreign Service personnel on official orders. Federal rules from USDA APHIS, the CDC and the U.S. Department of Transportation (DOT) apply on top of airline policy.

Put simply, American Airlines animal transport is the set of airline services and federal rules that decide whether an animal flies beside you, in the hold or as freight. This guide explains each route, who regulates it, and what happens if something goes wrong. As of October 2026, it reflects American Airlines, American Airlines Cargo, CDC, USDA APHIS and eCFR pages that we reviewed on October 4, 2026. If you mainly need cabin fees and carrier sizes, read our companion guide, American Airlines Flying Pets: 2026 Rules and Fees.

What is American Airlines animal transport?

American Airlines moves animals in four ways. How an animal travels decides who has custody of it, which federal rules apply and what you pay. The table below summarizes American Airlines' published options as of October 2026.

Fees apply to each destination. If a trip has a stopover or connection of 4 hours or more, American charges the fee again for each connecting segment. All pet fees are nonrefundable (American Airlines, 2026). A pet must also stay in the same category for the whole trip; American does not let you mix checked and cargo legs.

Cabin transport: carry-on pets and service dogs

Carry-on pets

American Airlines limits carry-on pets to cats and dogs that meet size, age and destination rules. The pet must stay in its carrier under the seat in front of you for the entire flight (American Airlines, 2026). Besides the carrier, you may bring either a personal item or a carry-on bag, but not both. You add the pet through the Additional Services section of your trip on aa.com or the American app, then pay at the ticket counter.

Cabin pets are not allowed on trans-Atlantic or trans-Pacific trips, to or from Hawaii, to Jamaica, or to or from Argentina, Brazil, Chile, Colombia and Uruguay (American Airlines, 2026). Most mainline jets carry no more than 20 pet carriers across all cabins. American Eagle regional jets allow 1 carrier in the premium cabin and 5 in the Main Cabin.

Service animals

American Airlines defines a service animal as a dog individually trained to do work or perform tasks for a qualified individual with a disability. Emotional support animals, comfort animals and service animals in training travel as pets and pay pet fees (American Airlines, 2026). American recommends submitting the DOT Service Animal Air Transportation Form at least 48 hours before the flight. On flights over 8 hours, the DOT Service Animal Relief Attestation Form is also required. Once a form is approved, American issues a Service Animal ID (SVAN ID) that can be reused until the dog's vaccination expires. Each passenger may bring up to 2 service animals, and each must be at least 4 months old.

Hold and cargo transport: checked pets and American PetEmbark

Checked pets are restricted

American Airlines accepts checked pets at the ticket counter only for active-duty U.S. military and U.S. State Department Foreign Service personnel traveling on official orders. Each eligible traveler may check up to 2 pets, first come, first served (American Airlines, 2026). The traveler must contact Reservations at least 48 hours ahead and check in 2 to 4 hours before departure. They also need a veterinary health certificate issued within 10 days of travel. The pet and kennel together cannot weigh more than 100 lbs (45 kg).

American PetEmbark: the cargo route most pets use

American PetEmbark is American Airlines Cargo's pet shipping service for animals that don't qualify to travel as carry-on or checked pets. American Airlines Cargo recommends booking at least 24 hours and no more than 10 days before travel (30 days for pets flying into London Heathrow). It takes no payment until the pet is accepted at the airport (American Airlines Cargo, 2026). Depending on size and route, a pet travels under one of two products: Priority Parcel Service (PPS) or ExpediteFS.

American Airlines Cargo publishes a seven-step process:

1. Confirm eligibility. Dogs flying domestically on American must be at least 8 weeks old, and dogs flying internationally at least 6 months old. Check that the breed isn't restricted, the route and aircraft are compatible, and forecast temperatures are 85°F or lower.
2. Choose a compliant kennel. It must meet American Airlines Cargo's construction guidelines.
3. Request a booking. Sign up for email notifications so you receive tracking updates.
4. Drop off. Offer a light meal and water within 4 hours before drop-off, attach a bag of food to the kennel, and bring 2 forms of identification and all health certificates. American Airlines Cargo will not accept household dogs and cats that have been sedated or tranquilized.
5. Track. Use the air waybill number on aa.com.
6. Pick up. Pets are typically ready about one hour after arrival. International shipments may add customs clearance and handling fees.
7. Reunite. Collect the pet with your air waybill number and identification.

Temperature and breed embargoes

American Airlines will not carry a pet outside the cabin if the current or forecast temperature is above 85°F (29.4°C) anywhere on the itinerary. Between May 1 and September 30, pets not flying in the cabin cannot travel to, through or from Phoenix (PHX), Tucson (TUS), Las Vegas (LAS) or Palm Springs (PSP) (American Airlines, 2026). The cold limit is 45°F (7.2°C). A veterinarian's acclimation letter can waive it, but no pet can be checked below 20°F (-6.6°C), even with a letter. American also refuses brachycephalic (snub-nosed) cats and dogs of any mix as checked pets. These include Persians, pugs, bulldogs, boxers and mastiffs.

Who regulates animal transport on American Airlines?

Airline policy is only one layer. Four public bodies set the rules underneath it.

USDA APHIS and the Animal Welfare Act

The United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) enforces the Animal Welfare Act (AWA) during transport. APHIS says any airline that carries covered animals "under the plane or as cargo" for hire is regulated and must register with APHIS (USDA APHIS, page last modified April 17, 2026). The same page says pets that travel in the cabin with their owner are not regulated under the AWA. So the federal welfare standards apply to the PetEmbark and checked routes, not to carry-on pets.

For dogs and cats, the standards are in 9 CFR Part 3, Subpart A (eCFR, 2026). Several of American's own rules come straight from them:

• Carriers must not accept a dog or cat more than 4 hours before scheduled departure. The consignor may agree to extend this by up to 2 hours.
• The consignor must certify in writing that the animal was offered food and water within the 4 hours before handover, with feeding instructions covering 24 hours. "No food or water" instructions are allowed only if a veterinarian directs them.
• Kennels must be marked "Live Animals" in letters at least 1 inch (2.5 cm) high, with upright arrows.
• Cargo areas must be heated or cooled as needed and pressurized in flight, except when flying under 8,000 feet.
• If the consignee cannot be notified within 24 hours of arrival, or does not collect the animal within 48 hours of being notified, the carrier must return the animal to the consignor.

U.S. Department of Transportation incident reporting

Under 14 CFR Part 235, U.S. airlines that run scheduled passenger service with at least one aircraft of more than 60 seats must report every loss, injury or death of an animal in their custody to DOT's Aviation Consumer Protection Division. Reports are due within 15 days after the end of each month (eCFR, 2026). Each December report must also give the year's totals for deaths, injuries and losses, plus the total number of animals transported. The rule's definition of "air transport" excludes animals at a passenger's seat in the cabin, so carry-on pets are not counted. DOT publishes the airline reports in its monthly Air Travel Consumer Report. If you are comparing carriers, this is the official dataset to use, not anecdotes.

CDC and dogs entering the United States

The U.S. Centers for Disease Control and Prevention (CDC) is the primary authority for dogs entering or returning to the United States. Its requirements depend on where the dog was vaccinated and whether it was in a high-risk country for dog rabies during the previous 6 months (CDC, rules effective August 1, 2024). A dog that has been in a high-risk country in that period and is not vaccinated will not be allowed into the U.S. American Airlines adds its own restriction: it does not accept dogs as carry-on pets if they come from, or have visited, a high-risk rabies country in the 6 months before travel. Service dogs that meet CDC requirements are exempt.

IATA Live Animals Regulations

The International Air Transport Association (IATA) publishes the Live Animals Regulations (LAR). The industry uses them as the reference for container design, documentation, stocking density and handling for every kind of animal: pets, day-old chicks, racehorses, laboratory animals and livestock. IATA says changes in the 53rd edition (2027) include updated container dimensions for snub-nosed breeds and new ventilation standards (IATA, 2026). International PetEmbark shipments, and any commercial live-animal shipment, are built around these standards.

Can livestock or exotic animals fly on American Airlines?

American Airlines' public pet pages are written for household companion animals, and cabin transport is limited to cats and dogs. USDA APHIS also draws a firm line. Animals considered livestock or poultry, such as pigs and chickens, do not qualify for pet travel and fall under separate import and export regulations (USDA APHIS, page last modified March 20, 2026). Chickens, ducks, geese, pigeons, quail and turkeys are regulated as poultry, not pets.

In practice, moving livestock, zoo animals or other commercial live animals by air is a freight matter, not a passenger matter. It usually involves an IATA-trained freight forwarder, a USDA-endorsed export health certificate and the destination country's import permit. Consumer pet guides often skip this distinction. If you plan to ship a non-pet animal, contact American Airlines Cargo directly before making any other arrangements.

Step-by-step: planning an American Airlines animal shipment

1. Classify the animal. Decide whether it is a pet, a service dog, or livestock or poultry under the USDA APHIS definitions. That answer decides which rules apply.
2. Pick the route. Choose cabin if the pet fits under the seat, checked if you are on official military or State Department orders, and PetEmbark otherwise.
3. Check the destination. Confirm country, state and airport restrictions, such as Hawaii's Honolulu-only entry, the New World Screwworm certificate for dogs going to Mexico, and Heathrow's cargo-only rule for pets.
4. See a USDA-accredited veterinarian early. USDA APHIS advises contacting one as soon as you decide to travel internationally.
5. Prepare the kennel and paperwork. You need the health certificate, the feeding certification and, if needed, a cold-acclimation letter.
6. Watch the weather. Re-check forecasts against the 85°F and 45°F limits for every airport on the itinerary.
7. Keep your own records. Keep copies of the air waybill, health certificate and identification photos until the animal is home.

Where Animal Passport fits, and where it does not

None of the documents above is issued by Animal Passport, and Animal Passport does not replace any of them. An airline booking, a veterinary health certificate, a CDC Dog Import Form and a USDA-endorsed export certificate are official requirements. Animal Passport is not an airline travel document, a government-issued pet passport or a substitute for a microchip or health certificate.

What Animal Passport does is identity. It is a digital animal and livestock passport built on muzzle biometrics, because an animal's nose print is unique, much like a human fingerprint. An owner captures it with a phone. The record links owner, breed, estimated age, body condition and vaccination history. Age is estimated from a dental photograph and comes with a confidence score. Body condition is scored from 1 to 5 using a side-profile photo.

That kind of record matters most when physical identifiers fail. During the August 2025 floods in Pakistan, Animal Passport was used in livestock rescue so farmers could reclaim animals after their paper tags washed away. For owners shipping animals, the takeaway is simple: keep an identity record that does not depend on a tag, a collar or a piece of paper surviving the trip.

How we researched this article

Every fee, limit and rule in this article comes from official pages we opened on October 4, 2026: American Airlines' pets and service animal pages, American Airlines Cargo's PetEmbark guide, the CDC, USDA APHIS, the electronic Code of Federal Regulations (eCFR) and IATA. Two of American's official sources differ on minimum age. The pets page sets 8 weeks for cats and dogs within the U.S. and Puerto Rico, while the cargo guide sets 6 months for dogs flying internationally. Check which one applies to your route. Airline rules change often, so confirm with American Airlines before you fly. This article is general information, not veterinary or legal advice.
