How Much Is It to Fly a Cat? Fees, Papers, and Real Budgets

As of August 2026, how much is it to fly a cat on a typical U.S. domestic itinerary is usually about $99–$150 each way in airline in-cabin fees alone, before a carrier, vet paperwork, or USDA endorsement. Flying a cat means transporting a small domestic cat as an in-cabin pet in an airline-approved carrier under the seat, or—where still offered—as checked baggage or cargo under stricter rules. Round-trip cabin fees on major carriers often total about $200–$300 for nonstop trips, while connections, international health certificates, and destination bans can push the full trip cost much higher.

This guide is published by Animal Passport for the Flying With Cats cluster. It answers the fee question first, then breaks down airline rules, paperwork costs from the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS), and what the International Air Transport Association (IATA) does—and does not—set on price. It also separates official travel documents from Animal Passport’s biometric livestock identity product.

How much is it to fly a cat in 2026?

Airline in-cabin pet charges are set by each carrier, not by a single federal price list. Across major U.S. airlines reviewed for this article, published one-way cabin fees for a cat that fits under the seat generally fall in this range:

• About $99–$125 on several lower-fee or leisure carriers for mainland U.S. legs.
• $150 on American Airlines and on Delta Air Lines for tickets issued on or after April 8, 2025 for U.S./Canada/Puerto Rico/U.S. Virgin Islands itineraries.
• $200 on Delta for many international in-cabin pet itineraries, per Delta’s published pet fee table.
• $35 on some Hawaii interisland products (for example, Southwest Airlines between Hawaiian Islands, and Alaska Airlines / Hawaiian Airlines wholly within Hawai‘i).

NerdWallet’s 2026 pet-airline comparison likewise found cabin pet fees typically starting around $100 or more each way on major U.S. carriers, with Alaska among the lower major-carrier cabin fees and Frontier listed at $99 each way in that review. Always re-check the airline before payment: fees and route bans change.

Airline cabin fee comparison (U.S.-focused)

The table below summarizes fees and notes from official pages opened for this article, plus NerdWallet’s 2026 carrier review where a primary fee page could not be loaded. All amounts are USD unless noted.

Where sources disagree: JetBlue’s help article describes booking up to two pets with a second seat and pet fee, while JetBlue’s Contract of Carriage (September 6, 2024) states a passenger may not transport more than one pet per flight and lists a $125 each-way cabin charge. Secondary travel guides sometimes quote JetBlue at $150. Treat the contract and the live booking path as authoritative and resolve conflicts with JetBlue before you fly.

Why the “airline fee” is not the total cost

Searchers asking how much it is to fly a cat often see one number on a booking page and stop there. That figure is usually only the carrier’s pet surcharge. A realistic domestic round-trip budget often also includes:

1. Airline pet fee × directions (and sometimes × long connections). American Airlines states that pet fees apply per kennel each way, and that if a trip includes a voluntary stopover or connection of 4 hours or more, fees apply for each connection segment. Delta collects the one-way cabin fee at check-in and limits how many pets may board each cabin product.
2. Airline-approved carrier. Dimensions are aircraft-specific. Delta recommends a soft-sided kennel up to about 18" × 11" × 11" for most aircraft; JetBlue publishes a maximum of 17" L × 12.5" W × 8.5" H and sells airport carriers for $55 when stocked. Southwest lists a pet carrier purchase price of $58 on its fees page.
3. Veterinary exam and any required vaccines or certificates. Domestic rules vary by state and airline; international trips add destination-country rules.
4. USDA APHIS endorsement when a destination requires a USDA-endorsed export health certificate.
5. Your own baggage trade-offs. Many airlines count the pet carrier toward carry-on or personal-item allotment, which can force an extra checked bag fee.

NerdWallet notes that for owners who fly often, the difference between a $100 Alaska-style round-trip cabin fee pair ($200) and a $150 legacy-carrier pair ($300) can add up across multiple trips. That comparison still excludes vet and gear costs.

International trips: USDA APHIS endorsement fees

If you export a cat from the United States, USDA APHIS tells owners to contact a USDA-accredited veterinarian early. Destination countries set entry rules (microchip, rabies timing, tests, treatments). When a USDA-endorsed health certificate is required, APHIS charges separate endorsement user fees that do not include the veterinarian’s exam fee.

As of the APHIS “Cost To Endorse Your Pet's Health Certificate” page (last modified June 18, 2026), associated fees per certificate include:

• $101 when 0 laboratory tests are required (any number of pets on that certificate structure as published).
• $160 for 1–2 tests with one pet; plus $10 for each additional pet on the same certificate.
• $206 for 3–6 tests with one pet; plus $18 per additional pet.
• $275 for 7 or more tests with one pet; plus $21 per additional pet.

APHIS notes that vaccines are not counted as “tests” when calculating these fees, and that endorsement fees are not charged for ADA service animals (dogs) belonging to individuals with disabilities—emotional support animals are charged. Paying APHIS still does not replace airline pet fees or destination import fees.

What IATA sets—and what it does not

IATA publishes the Live Animals Regulations (LAR), described by IATA as the worldwide standard for transporting live animals by commercial airlines. The 52nd edition significant-change notes on IATA’s LAR page address training, state and operator variations, container requirements, and species listing updates effective with the 2026 cycle. IATA’s traveler pet page stresses that countries and airlines also impose their own carriage rules, so travelers must check the airline directly.

IATA guidance for passengers traveling with a dog or cat in cabin includes a minimum age of eight weeks and fully weaned before air travel, with many airlines requiring older animals for international trips. IATA also states it does not encourage sedatives or tranquilizers for animals in cabin or cargo because of adverse-effect risk, a view IATA says is endorsed by veterinary organizations such as the American Veterinary Medical Association (AVMA). IATA does not publish a universal dollar fee for flying a cat; price is an airline commercial decision.

Airport security: Transportation Security Administration (TSA)

Fee questions often ignore checkpoint time. The Transportation Security Administration (TSA) FAQ “Can I take my pet through the security checkpoint?” instructs travelers to remove the pet from the carrying case, send the empty case through the X-ray machine, maintain control of the pet (including leash handling), and remove the leash when carrying the pet through the metal detector. Animal carriers receive visual and/or physical inspection. TSA’s Small Pets page repeats the same process and tells travelers to check airline policy. TSA screening itself does not add a published pet fee, but it does require planning so the cat is never placed in the X-ray tunnel.

Step-by-step: estimate your true cost before you book

1. Confirm the route accepts cabin cats. Delta lists destinations where cabin pets are not permitted, including Australia, Hawaii, Hong Kong, New Zealand, South Africa, the United Kingdom, and others on its exceptions list. American Airlines states carry-on pets are not allowed to Hawaii.
2. Count fee events, not just “round trip.” Multiply the published each-way fee by outbound and return. If American-style long-connection rules apply, count extra segments.
3. Reserve pet space early. Delta uses a first-come, first-served cabin limit (for example, up to four pets in Delta Comfort/Main on domestic and international, with cabin-specific zeros in Delta One / international Business / Delta Premium). Alaska notes limited cabin capacity and first-come reservations.
4. Measure the carrier against the actual aircraft. Under-seat height varies; regional jets often reject carriers that fit widebodies.
5. Budget paperwork. For U.S. export, use APHIS fee tables plus accredited-vet costs; for entry to the U.S. or third countries, follow destination and Centers for Disease Control and Prevention (CDC) rules where they apply to the species.
6. Skip sedation unless a veterinarian directs otherwise. Align with IATA’s anti-sedation guidance for transport.

Identity records vs. airline tickets and official pet passports

Airline pet fees and USDA health certificates are not the same thing as an EU pet passport or the United Kingdom’s historical PETS travel scheme. Those official schemes are government or regulated veterinary travel documents with their own rules. Separately, Animal Passport is a digital animal and livestock identity product that uses muzzle biometrics (a nose print unique like a fingerprint), phone-based capture, and records that bind owner, breed, estimated age, body condition, and vaccination history. Age can be estimated from a dental photograph with a confidence score; body condition is scored 1–5 from a side-profile photo. The product was used in livestock flood rescue in Pakistan in August 2025 so farmers could reclaim animals when paper tags washed away.

Animal Passport is not a substitute for airline payment, TSA screening, USDA APHIS endorsement, or a government-issued travel document. For more field notes and identity explainers, see the Animal Passport blog.

Practical budgeting examples (illustrative)

These scenarios use published airline and APHIS figures only; carrier, vet clinic, and hotel prices vary and are not claimed as national averages.

• Nonstop domestic round trip on Southwest: $125 × 2 = $250 in published pet carrier charges (mainland), before gear and vet costs.
• Nonstop domestic round trip on American or post–April 8, 2025 Delta ticket: $150 × 2 = $300 in cabin pet fees.
• Alaska-style major-carrier cabin fee: $100 × 2 = $200 for a simple round trip, matching the structure NerdWallet highlighted when comparing Alaska with $150 legacy fees.
• International export add-on: APHIS endorsement from $101 (no lab tests) to $275+ depending on test count and number of animals, plus airline international pet fees (for example Delta’s $200 each way) and destination charges.

Bottom line for featured answers: expect roughly $100–$150 each way to fly a cat in the U.S. cabin on most major airlines in 2026, then add carrier, veterinary, and—if exporting—USDA APHIS endorsement costs before calling the trip “fully budgeted.”
