Cost to Fly a Cat on a Plane: 2026 Fees, Vet Paperwork, and Total Budget

The cost to fly a cat on a plane is typically $95 to $200 each way in airline pet fees on major U.S. carriers as of 2026, according to airline policy pages from Delta, United, American, Southwest, and Alaska Airlines. That fee covers the cat riding in an approved carrier under the seat in front of you. It does not include the carrier itself, veterinary paperwork, or extra costs for international trips, which can push the total budget for one flight well past $500.

This guide breaks down exactly what you pay for a domestic flight versus an international one, using each airline's own published rates and the federal fee schedule from the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS). It also clarifies where a European Union pet passport fits in, and how that official travel document differs from Animal Passport's biometric livestock identification product.

Airline In-Cabin Pet Fees by Carrier (2026)

Airline pet fees are charged per carrier (not per cat, in most cases), each way, and are separate from your own ticket price. Here is what the major U.S. airlines currently publish on their pet-travel pages.

Because these fees change with fare rules and route, always confirm the current published rate on the airline's own pet-travel page before you book, rather than relying on a fixed number from any article, including this one.

What Else Adds to the Total Cost

The carrier

Airlines require a carrier that fits under the seat and meets size limits (commonly around 18" x 11" x 11", though exact dimensions vary by airline). An airline-compliant soft-sided carrier generally costs $30-$100 and is a one-time purchase, not a per-flight fee.

Domestic health paperwork

Most U.S. domestic flights do not require a USDA-endorsed certificate. However, some states require a Certificate of Veterinary Inspection (CVI) for interstate pet travel, which a licensed veterinarian issues after an exam. This typically costs roughly $100-$350 depending on the clinic and state, according to veterinary-practice pricing summaries. Check with your destination state's animal health office if you are unsure whether one is required.

International health certificates and APHIS fees

Flying a cat internationally requires an export health certificate completed by an accredited veterinarian and, for most countries, endorsed by USDA APHIS. As of 2025, APHIS charges a federal endorsement fee of $101 per certificate when no laboratory tests are required, rising to $160 for one to two tests, $206 for three to six tests, and $275 for seven or more tests, per APHIS's official "Cost To Endorse Your Pet's Health Certificate" page. This endorsement fee is separate from, and smaller than, the veterinarian's own exam and paperwork fee, so the all-in cost of a certificate for international travel commonly lands between roughly $150 and $560, and can run higher for destinations with extra testing requirements such as a rabies antibody titer.

Airport security

The Transportation Security Administration (TSA) does not charge a screening fee for pets. At the checkpoint, TSA requires you to remove your cat from the carrier and carry it or walk it on a leash through the metal detector while the empty carrier goes through the X-ray machine, per TSA's official "Small Pets" guidance. Travelers with a skittish cat can request private screening.

Domestic vs. International: Total Budget Comparison

Cats to the European Union: A Different, Official Process

If your cat is entering the European Union, the relevant document is not a USDA form but the EU Pet Travel Scheme. Under the European Commission's official rules, a cat moving between EU countries needs an EU pet passport containing microchip, rabies vaccination, and owner details, while a cat entering the EU from a non-EU country needs an EU animal health certificate issued by an official vet no more than 10 days before arrival, per the European Commission's "Travelling with pets and other animals in the EU" guidance (Your Europe portal). Cats must also be microchipped, rabies-vaccinated at 12 weeks or older with a 21-day wait before travel, and, from many non-EU countries, pass a rabies antibody titration test. UK pet-industry pricing guides put the full cost of the vet exam, microchip check, and Animal Health Certificate at roughly £150-£350 (about $190-$440) per cat, though this is a one-off cost rather than a per-flight fee.

This EU document is unrelated to Animal Passport's product. Animal Passport is a digital biometric identification tool built around a phone-captured muzzle print, the nose pattern that is unique to each animal, similar to a human fingerprint, paired with an estimated age from a dental photo and a body condition score from a side-profile image. It was used during livestock flood rescue efforts in Pakistan in August 2025 to help farmers reclaim animals after paper ear tags were washed away. It is a livestock identity record, not an airline-recognized or government-issued pet travel document, and it does not substitute for a USDA health certificate or an EU pet passport when flying a cat.

How to Budget for Flying With a Cat: 5 Steps

1. Check your airline's current pet fee on its official pet-travel page, since rates in this article can change without notice.
2. Buy an airline-compliant carrier that fits the exact dimensions your airline lists for under-seat storage.
3. Confirm whether your route needs paperwork. Most U.S. domestic flights need none; check your destination state if traveling interstate.
4. Book a USDA-accredited vet visit early for international trips, since some countries require testing, like a rabies titer, that must happen months before travel.
5. Budget the APHIS endorsement fee separately from the vet's exam fee, since APHIS bills $101-$275 per certificate depending on testing, per USDA APHIS.

Frequently Asked Questions

How much does it cost to fly with a cat in the cabin?

Most major U.S. airlines charge $95-$200 each way for a cat in an approved carrier under the seat, according to each airline's published 2026 pet-travel page. The exact fee depends on the airline and whether the flight is domestic or international.

Is it cheaper to fly a cat as cargo instead of in the cabin?

Not usually an option on most major U.S. passenger airlines today. United suspended its PetSafe cargo program for the general public in 2018 and now limits checked pet transport largely to military and State Department relocations, so cabin travel is the standard, and often only, route for cats on large U.S. carriers.

Do I need a health certificate to fly domestically with my cat?

Often not for the airline itself, but some states require a Certificate of Veterinary Inspection for interstate pet travel. Check your destination state's animal health requirements before you fly, since airlines don't always enforce this but state law may.

How much does a USDA health certificate cost for international cat travel?

The APHIS federal endorsement fee alone is $101 per certificate with no lab tests, rising to $160, $206, or $275 depending on how many laboratory tests are required, per USDA APHIS's official fee page. Add the veterinarian's own exam and paperwork charge, and the realistic total is commonly $150-$560 or more.

Does TSA charge extra to screen a cat at security?

No. TSA does not charge a fee to screen pets, but you must take your cat out of the carrier and carry or walk it through the metal detector while the empty carrier goes through the X-ray machine, per TSA's official guidance.

Is an EU pet passport the same as Animal Passport's product?

No. The EU pet passport is an official European Commission travel document tied to microchip and rabies vaccination records. Animal Passport is a separate biometric livestock identification tool built on muzzle prints; it is not a government-issued or airline-recognized travel document.

Can I bring my cat as a carry-on item, or does it count separately?

On most U.S. airlines, the cat's carrier counts as your one permitted carry-on bag, so you generally cannot bring a separate roller bag in addition to the pet carrier.

What is the cheapest way to fly domestically with a cat?

Based on published 2026 rates, Alaska Airlines' $100 each-way in-cabin fee is the lowest among the major U.S. carriers compared here, versus $125-$200 on Southwest, United, American, and Delta.

Bottom Line

For a routine domestic round trip, plan on roughly $200-$400 total once you add the airline's in-cabin fee both ways to a one-time carrier purchase. For international travel, plan closer to $600-$1,200 or more once you include the veterinarian's exam, any required lab testing, and the USDA APHIS endorsement fee, or the equivalent EU Animal Health Certificate process if you're flying into the European Union. As of September 2026, always verify the current fee on the airline's own page before booking, since pet fees have changed more than once in the past year across several major carriers.
