You booked the trip, and now there’s a small, furry question sitting in the litter box: what’s it actually going to cost to bring your cat along? If you’ve been guessing, you’re not alone. Airline pet pages bury the number, and every carrier does it a little differently.
Here’s the honest breakdown. Flying with a cat in the cabin is not free, but it’s rarely as scary as the internet makes it sound. Most cat parents spend somewhere between $200 and $400 all-in for a domestic round trip once you count the airline fee, a carrier, and a quick vet visit. Let’s walk through exactly where that money goes.
This article is educational. Airline fees and pet rules change often, so always confirm the current policy on your airline’s own pet page before you book.
- In-cabin cat fees on major US airlines run about $99 to $150 each way, and the fee is charged per direction, not per trip.
- Alaska ($100) and Frontier ($99) are the cheapest major airlines for flying with a cat in the cabin.
- A connecting flight usually means paying the pet fee twice each way, so a round trip with connections can cost four times the one-way fee.
- A domestic health certificate typically costs $50 to $150 at the vet, and many airlines don’t require one for cabin travel within the US.
- Cargo shipping a cat costs far more, often $500 to $1,000+, and most cat parents should keep their cat in the cabin instead.
How much does it cost to bring a cat on a plane?
Bringing a cat on a plane in the cabin costs roughly $99 to $150 each way on major US airlines, plus a few one-time extras. The airline pet fee is the biggest recurring cost, and it’s charged separately for each direction you fly. Budget another $30 to $70 for an approved carrier and $0 to $150 for a health certificate, depending on your route and airline.
Here’s a realistic picture of a domestic round trip: two $125 pet fees ($250), a $45 carrier you’ll reuse for years, and maybe a $60 vet visit. That’s about $355 total, and the carrier is a one-time buy. Fly a budget airline like Frontier and the same trip drops closer to $250.
One thing that catches people off guard: the fee is per segment on most airlines. If your flight connects, you pay the pet fee for each leg. A nonstop each way is the cheapest way to fly with a cat, and it’s also the calmest option for your cat.
In-cabin cat fees by airline (2025 to 2026)
In-cabin pet fees vary a lot by airline, from about $99 on Frontier to $150 on American, Delta, and United. The table below shows current one-way, in-cabin fees for a cat on the major US carriers. These are the fees for a small cat that rides under the seat in front of you, which is how nearly all cats fly.
| Airline | In-cabin fee (one way) | Notes |
|---|---|---|
| Frontier | ~$99 | Charged each way; per segment |
| Alaska | ~$100 | One of the cheapest majors; allows 2 cats per carrier |
| Southwest | ~$125 | Lower fee on some Hawaii routes |
| JetBlue | ~$125 | Earns TrueBlue points on the pet fee |
| Spirit | ~$125 | Charged each way; per segment |
| American | ~$150 | Charged each way; per segment |
| Delta | ~$150 | Raised from $95 in April 2025 |
| United | ~$150 | Charged each way; per segment |
Fees change, sometimes with little warning. Delta bumped its in-cabin pet fee from $95 to $150 in April 2025, so always double-check the number on your airline’s official pet policy page, like Delta’s pet travel overview or United’s traveling with pets page, before you commit. Prices here reflect late-2025 policies and are meant as a planning guide, not a quote.
Why the fee can double or quadruple
The listed fee is per direction, and often per segment, so your real cost depends on your route. A nonstop round trip means two fees. A round trip with one connection each way can mean four fees on airlines that charge per segment. When you’re comparing airlines, always do the math on your actual itinerary, not just the sticker fee.
Is it cheaper to fly a cat in the cabin or as cargo?
Flying a cat in the cabin is almost always cheaper and safer than shipping them as cargo. In-cabin travel runs about $99 to $150 each way, while cargo or checked-pet service typically costs $200 to $1,000 or more, depending on the cat’s weight, the route, and whether the cat travels accompanied or as unaccompanied cargo.
For a healthy cat small enough to fit in an under-seat carrier (usually under about 15 to 20 pounds with the carrier), the cabin is the clear winner. Your cat stays with you, in a pressurized and temperature-controlled space you can see and reach. Most airlines actually won’t fly cats in cargo anymore for domestic passengers, reserving cargo for specific situations like international moves or military and relocation shipments.
| Option | Typical cost | Best for |
|---|---|---|
| In-cabin (under seat) | $99 to $150 each way | Almost every pet cat on a domestic flight |
| Checked pet / cargo | $200 to $1,000+ | Cats too large for the cabin, or some international moves |
| Pet relocation service | $1,000 to $3,000+ | Complex international moves with paperwork handled for you |
What are the carrier requirements, and what does a carrier cost?
Airlines require a soft-sided, leak-proof, well-ventilated carrier that fits fully under the seat in front of you, and a good one costs about $30 to $70. Your cat has to be able to stand up and turn around inside it, and it counts as your personal item or carry-on. Hard-sided carriers are allowed by some airlines but often don’t squish under the seat as well as a soft one.
Under-seat space is tight and varies by airline. Most cap soft carriers around 17 to 18.5 inches long, 11 to 14 inches wide, and 8 to 11 inches tall. A carrier that’s perfect on Alaska might be an inch too tall for JetBlue, so measure against your specific airline’s limit before you fly.
- Soft-sided and flexible: squishes to fit tight under-seat spaces.
- Ventilation on at least two sides: three or four sides for international routes.
- Leak-proof bottom: a removable, absorbent pad is a lifesaver.
- Fits your airline’s exact dimensions: check the number, don’t eyeball it.

Do I need a health certificate, and what does it cost?
Most US airlines do not require a health certificate for a cat flying in the cabin on a domestic flight, but a few do, and nearly all international trips require one. When you need it, a domestic health certificate (also called a Certificate of Veterinary Inspection, or CVI) typically costs $50 to $150, on top of the regular vet exam fee.
A health certificate is a document from a licensed vet confirming your cat is healthy and up to date on vaccines like rabies. Timing matters: many airlines only accept a certificate issued within 10 days of travel, so don’t get it too early. International certificates cost much more, often $200 to $600+ once you add required testing and USDA endorsement, and the rules depend entirely on the destination country.
While you’re at the vet, it’s a smart time to confirm your cat’s microchip is current, since some destinations and airlines ask for it. If you haven’t done that yet, here’s what it costs to microchip a cat. For general trip-prep guidance, the American Airlines’ pet policy are a solid, vet-informed starting point.
What are the hidden and extra costs of flying with a cat?
The airline fee is just the headline number. A handful of smaller costs add up, so it helps to budget for them upfront rather than getting surprised at the counter. Here’s what else tends to land on the bill.
- Pre-travel vet visit: $50 to $100 for a wellness check and any needed vaccines.
- Health certificate: $50 to $150 domestic when required, more for international.
- Carrier: $30 to $70, though it’s a one-time buy you’ll reuse.
- Calming aids: $10 to $30 for vet-approved calming treats, a pheromone spray, or a familiar blanket.
- Second pet fee: if you fly two cats, most airlines charge a full fee for each.
- Connection fees: extra pet charges on each segment if your route isn’t nonstop.
Never give your cat a sedative before a flight without your vet’s okay. The American Veterinary Medical Association notes that sedatives can raise the risk of breathing and heart problems at altitude, which is why most vets steer cat parents toward calming aids and desensitization instead. Talk to your vet about what’s safe for your specific cat.
How can I save money flying with my cat?
The easiest way to save is to choose a lower-fee airline and book nonstop so you pay the pet fee once each way instead of two or three times. A little planning around the fee structure often saves more than any coupon.
- Pick a budget-friendly airline. Frontier and Alaska sit near $99 to $100 each way, versus $150 on the big three.
- Fly nonstop. Connections can double or triple the pet fee on per-segment airlines.
- Buy the carrier once. A durable, airline-approved carrier lasts years, so cost-per-trip drops fast.
- Skip the certificate when it’s not required. Many domestic cabin flights don’t need one, so confirm before paying for it.
- Reserve your pet spot early. Airlines cap the number of pets per flight, and getting bumped can force a pricier rebooking.
- Watch the extras. A familiar blanket and vet-approved calming treats beat expensive gadgets for keeping your cat calm.
Cost of flying with a cat FAQ
Q: How much does it cost to fly with a cat one way?
A one-way, in-cabin cat fee runs about $99 to $150 on major US airlines. Frontier and Alaska are near the low end at $99 to $100, while American, Delta, and United charge around $150. The fee is charged per direction and often per connecting segment.
Q: Which airline is cheapest for flying with a cat?
Frontier (about $99 each way) and Alaska (about $100 each way) are typically the cheapest major US airlines for an in-cabin cat. Alaska also lets two small cats share one carrier, which can save a full fee if you’re traveling with a bonded pair.
Q: Does a cat count as a carry-on?
Yes. On most airlines the cat carrier counts as your carry-on or personal item and must fit fully under the seat in front of you. That means you’ll usually check a bag or limit yourself to one other small item to stay within the airline’s limits.
Q: Do I need a health certificate to fly with my cat domestically?
Often no, but it depends on the airline. Many US carriers don’t require a health certificate for a cat in the cabin on a domestic flight, while a few do. When required, a domestic certificate costs about $50 to $150. Always confirm your airline’s rule before travel.
Q: Is it safe to fly with a cat?
Flying in the cabin is generally safe for a healthy adult cat, since the cabin is pressurized and temperature-controlled and your cat stays with you. Talk to your vet first if your cat is very young, senior, or has heart or breathing issues, and never sedate a cat before a flight without veterinary guidance.
Q: How much does it cost to fly a cat internationally?
International cat travel costs much more than domestic. Expect the in-cabin fee plus $200 to $600+ for a health certificate with required testing and USDA endorsement, and possibly more for microchipping, vaccines, and country-specific paperwork. Full-service pet relocation can run $1,000 to $3,000 or more.
Q: Can I buy a seat for my cat instead of putting them under the seat?
No. US airlines require cats to stay inside a closed, ventilated carrier under the seat in front of you for the entire flight. You can’t buy a separate seat for a cat or let them ride on your lap, so a well-fitted carrier is the only option.
Q: How many cats can I bring on a plane?
Most airlines allow one cat per carrier and cap the total pets per cabin, so book early. A few airlines, including Alaska, let two small cats share one carrier if they fit comfortably. You’ll still usually pay a separate pet fee for each carrier you bring.
Bottom line: flying with your cat costs less than most people fear. Budget around $99 to $150 each way for the airline fee, add a one-time carrier and a possible health certificate, and choose a nonstop on a lower-fee airline to keep the total down. Confirm the current fee on your airline’s pet page, and your cat will be napping under the seat before you know it.
