Can You Bring Your Cat on a Plane? Cabin Rules, Fees, and Documents

Yes—you can bring your cat on a plane on most major U.S. airlines if it rides in an approved carrier under your seat. Can you bring your cat on a plane depends on airline cabin rules, TSA screening, and destination health papers. As of September 2026, reserve the pet early, confirm carrier size for your aircraft, and check veterinary documents before you fly.

This guide from Animal Passport explains cabin versus cargo options, current published fees on selected carriers, TSA and FAA requirements, and how official pet travel documents differ from Animal Passport’s biometric livestock identity product. It is informational only and is not veterinary, legal, or government advice.

What “bringing a cat on a plane” means

Bringing a cat on a plane usually means booking the animal as an in-cabin pet (industry code PETC) so the carrier stows under your seat for the whole flight. The International Air Transport Association (IATA) states that, subject to airline policy, cats and dogs may travel in the cabin when they meet Container Requirement 1 (CR1) of the IATA Live Animals Regulations (LAR), according to IATA’s Operational Guidelines for In-Cabin Pet Transport. Larger cats, restricted routes, or airlines that ban cabin pets may require cargo (AVIH) or a specialized pet shipper instead.

The Federal Aviation Administration (FAA) confirms that each airline decides whether pets may ride in the passenger cabin. If the airline allows it, the pet container is treated as carry-on baggage under 14 CFR part 121, section 121.589, and must fit underneath the seat without blocking the aisle, be stowed before the last passenger door closes, and stay stowed while the airplane is moving on the surface and during takeoff and landing, according to the FAA’s Flying with Pets page (last updated December 4, 2025).

Cabin vs. cargo: how cats actually fly

American Airlines states that checked pets at the ticket counter are accepted only for active-duty U.S. Military and U.S. State Department Foreign Service personnel traveling on official orders; other larger pets may need American Airlines Cargo (American PetEmbark®), according to American Airlines’ Traveling with pets page. Delta Air Lines likewise emphasizes in-cabin pets for the general public and points military and Foreign Service travelers to separate hold options on its Pet Travel Overview. Southwest Airlines states that no pets are transported in the cargo compartment and that cabin pets are accepted on a first-come, first-served basis, according to Southwest Airlines’ Contract of Carriage.

How to fly with a cat in the cabin: step-by-step

1. Confirm the airline and route accept cats. Delta Air Lines lists destinations where in-cabin pets are not permitted—including Australia, Hawaii, the United Kingdom, and several others—on its Pet Travel Overview as of 2026. American Airlines also bars carry-on pets to or from Hawaii and on trans-Atlantic trips.
2. Reserve the pet space early. Airlines cap how many pets board each flight. Delta uses a first-come, first-served cabin limit and asks customers to call Reservations with kennel dimensions. Southwest reserves the right to limit pet carriers to six per flight and requires pet reservations by phone, according to its Contract of Carriage.
3. Choose a leak-proof, ventilated carrier that fits under the seat. IATA passenger guidance requires an IATA-compliant container that lets the cat sit erect, stand, turn around, and lie down in a natural position, with adequate ventilation and a leak-proof design. Delta recommends a soft-sided kennel with maximum dimensions of 18" × 11" × 11" because that size fits most aircraft types. American Airlines lists recommended soft-sided dimensions of 18 × 11 × 11 inches (46 × 28 × 28 centimeters).
4. Meet age and health rules. IATA advises that unweaned animals and animals under 8 weeks must not travel and that sedation or tranquilization is advised against for cabin travel. Southwest requires vaccinated domestic cats and dogs at least eight weeks old. Delta requires pets to be at least 8 weeks old for domestic travel and at least 15 weeks old when traveling to the European Union.
5. Gather health papers for the destination. For international export from the United States, the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) lists cats among animals that qualify as pets for pet-travel certification and requires a USDA-accredited veterinarian to issue health certificates that USDA may endorse through the Veterinary Export Health Certification System (VEHCS), according to USDA APHIS guidance last modified April 1, 2026. Destination countries set the exact vaccinations, microchip rules, and timing.
6. Arrive early, pay the pet fee, and clear TSA correctly. See the TSA section below. Keep the cat inside the carrier after screening except in designated relief areas when airline policy allows.

Published in-cabin fees on selected U.S. airlines (September 2026)

Fees change and are set by each carrier’s contract of carriage at ticket issuance. Always recheck the airline’s own site before booking.

These three carriers illustrate the market range for U.S. domestic cabin cats as of September 2026; other airlines publish different fees, carrier sizes, and destination bans. Policies can disagree on details such as whether a pet counts toward your free carry-on allowance, so read the ticketed carrier’s current page rather than assuming another airline’s rule applies.

TSA screening with a cat

The Transportation Security Administration (TSA) instructs travelers to remove the pet from the carrying case and place the empty case through the X-ray machine, maintain control of the pet with a leash, and remove the leash when carrying the pet through the metal detector; carriers also receive a visual and/or physical inspection, according to TSA’s FAQ “Can I take my pet through the security checkpoint?” TSA’s December 14, 2022 tip sheet adds that pets must never go through the X-ray tunnel, that owners should recompose away from the checkpoint after screening, and that airline pet policies still control whether the cat may board.

Health certificates, microchips, and EU pet passports

Domestic U.S. flights may or may not require a veterinary health certificate depending on the airline and destination state; international trips almost always do. USDA APHIS explains that destination countries set entry requirements and that USDA-accredited veterinarians issue export health certificates for endorsement when required. Airlines may also demand an APHIS Form 7001 or similar airline health form in addition to a country-specific certificate; USDA notes it typically endorses only the destination country’s required certificate, not a separate airline form, according to the USDA APHIS accredited-veterinarian guidance (April 1, 2026).

For travel between European Union countries with a dog, cat, or ferret, Your Europe (European Commission) requires a microchip (or a readable tattoo applied before July 3, 2011), a valid rabies vaccination, and a European pet passport issued by an authorised veterinarian to owners resident in the EU. Non-EU arrivals generally need an EU animal health certificate issued by an official veterinarian not more than 10 days before arrival in the EU, according to Your Europe’s pet travel page (last checked September 1, 2026). Commission food-safety pages cite Commission Delegated Regulation (EU) 2026/131 for non-commercial pet movements within the EU.

Animal Passport vs. an EU pet passport or airline pet ticket

Do not confuse official travel documents with Animal Passport’s product. An EU pet passport is a government-model identification booklet for dogs, cats, and ferrets that records microchip and rabies data for non-commercial movement under EU animal-health law. An airline pet reservation is a commercial carriage booking. Animal Passport is a digital animal and livestock identity system that uses muzzle biometrics (a nose print unique like a fingerprint), phone-based capture, and a record that can bind owner, breed, estimated age, body condition, and vaccination history. Age estimates come from a dental photograph with a confidence score, and body condition is scored 1–5 from a side-profile photo. The system was used in livestock flood rescue in Pakistan in August 2025 so farmers could reclaim animals when paper tags washed away. It is not a substitute for USDA APHIS export certificates, airline acceptance, TSA screening, or an EU pet passport unless an official authority expressly accepts it—and no such government travel endorsement is claimed here.

Practical preparation tips that reduce denied boarding

• Acclimate the cat to the carrier days or weeks ahead; IATA recommends introducing the container early so confinement stress is lower.
• Offer a light meal at least two hours before departure and a short drink and exercise before crating, consistent with IATA passenger guidance.
• Avoid sedatives unless a veterinarian directs otherwise and the airline is informed; IATA warns tranquillizers reduce an animal’s ability to respond to transport stress, and American Airlines states it does not accept sedated pets, citing American Veterinary Medical Association (AVMA) risk guidance.
• Book nonstop flights when possible and avoid exit-row or bulkhead seats that lack under-seat stowage, as the FAA and multiple airlines prohibit those seats for cabin pets.
• Carry vaccination records and any required certificates in print and digital form; timing windows for exams are often measured in days, not weeks.

When the answer is “not on this flight”

Even if the keyword question sounds yes/no, the operational answer can be no for a specific itinerary. Examples grounded in airline pages include Delta’s ban on in-cabin pets to or from the United Kingdom and Hawaii, American’s ban on carry-on pets on trans-Atlantic trips and to Hawaii, and Southwest’s cabin-only model with a six-carrier flight cap. International biosecurity rules in destinations such as Australia and New Zealand commonly force cargo or specialist import pathways rather than casual cabin travel. If sources disagree—for example, third-party blogs quoting older Delta fees of $95 versus Delta’s current $150 tier for tickets issued on or after April 8, 2025—prefer the airline’s live fee table and the ticket’s contract of carriage date.

As of September 2026, the safest workflow is: verify airline + aircraft + destination on primary pages the same week you travel, confirm USDA APHIS or EU entry rules with an accredited or authorised veterinarian, measure the carrier on the actual aircraft type, and build extra airport time for pet check-in and TSA screening.
