Pet Costs Cats

How much does it cost to fly a cat?

Work out what it actually costs to fly your cat, rather than what the airline's pet fee page says. It counts the in-cabin fee per flight instead of per trip, adds the checked bag you may have to buy because the carrier took your carry-on space, and puts the health certificate on the ledger with its expiry clock attached, because a trip longer than the certificate's window needs a second exam at the far end.

§ 01 Your numbers

Change anything. The answer updates as you type.

The figure on your airline's site for a pet in the cabin. Our default is ours and editable, a placeholder rather than an average of anything. Ask one question when you ring them: is the fee charged per flight segment or per direction? If they charge per direction, set the flights box below to 1 and put the whole one-way fee here.
Whether the cat is flying home again. It matters for more than doubling the fee: the return leg is the one that can outrun the health certificate and need a fresh exam.
1 for a nonstop. 2 if there is a connection. This is the box people forget, because the fee page quotes one number and the itinerary quietly multiplies it. A connection also means a longer day in a carrier for the cat, which is worth a thought that has nothing to do with money.
ASK YOUR AIRLINE, then set this. On many airlines the carrier under the seat uses the space your carry-on would have, so a bag you would have carried on gets checked instead, at a fee charged per flight. If your airline does not count it that way, or you were checking that bag anyway, leave this at zero. Our default is ours and is a placeholder.
What your vet charges for the visit and the certificate together. It has to be a vet accredited to write one, so your usual practice may or may not be able to, which is worth checking early rather than late. Our default is ours: ring your practice and replace it.
How long between the outbound flight and the return one. Compared against the certificate window below, this is what decides whether you buy one certificate or two.
YOUR number, from the rules for your route and your airline, not from us. The 10 is a placeholder so the form has something to draw. Windows differ by route and destination, and an international trip can be a different animal from a domestic one. Look yours up and type it in: if it is longer than your trip, the second certificate below disappears.
The soft carrier the cat travels in. Airlines set their own maximum dimensions for the space under a seat, and they are not all the same, so measure against your airline's stated size before buying. A carrier refused at the gate is a carrier you buy twice.
Absorbent pads for the carrier floor, a collapsible bowl, a harness for the security check, a disposable litter tray for the far end, and the labels. Small lines, but they are real and they land on the trip's bill rather than the cat's.

$500 to $1,200 is where the defaults land: a round trip, both airline lines charged twice, and either a displaced bag or a second certificate in the mix. Look at which of the two is doing it, because one is fixed by the airline's rules and the other by your dates.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

THE DEFAULTS ARE OURS. THE AIRLINE AND YOUR VET SET THE REAL NUMBERS.
Every line here is a quote from a company or a person: the airline's in-cabin pet fee, its checked bag fee, your vet's charge for an exam and a certificate, the price of a carrier that fits under a seat. All of them move with the airline, the route and where you live. We have put in figures we think are reasonable starting points and made every one editable, because the quote you have actually been given beats our placeholder every time. Nothing on this page comes from a federal statistic, because the cost of a cat's flight is a quote rather than something anyone measures.
THE BAG LINE IS A QUESTION FOR YOUR AIRLINE, NOT A RULE WE ARE STATING.
A carrier under the seat sits in the space a carry-on would have used, and on many airlines that means the bag you would have carried on gets checked instead. Whether yours counts it that way is theirs to say, so ring them and ask before you set the box. If the answer is no, or you were checking that bag regardless, put a zero in and the line vanishes. What the page is arguing is not that any particular airline charges you twice, but that the pet fee alone is not the airline's whole bill, and the difference is easy to find out in one phone call.

Both airline lines are charged per flight, and that is the itinerary moving the total rather than the cat. A nonstop round trip is two flights. One connection in each direction makes it four, and at our defaults that takes the total from $760 to $1,090, an extra $330 for an itinerary change the cat did not ask for. Ask the airline whether they price per flight segment or per direction, then set the flights box to match what they tell you.

THE CERTIFICATE WINDOW IS YOUR INPUT, AND WE ARE NOT STATING A RULE.
The 10 days is a placeholder so the form has a number to draw with. The window that applies to you comes from the rules for your route and your airline, and a domestic trip and an international one are not the same thing. Look yours up and type it in. The page's point survives whatever you find: not that the window is ten days, but that there is a window, that a trip can outrun it, and that the second exam then lands on you at the far end rather than at home. At our defaults a nine-day trip needs one certificate and a fourteen-day trip needs two, which brings the total from $760 down to $595 for a decision about dates.

This page prices the trip, not the alternative to it. A cat is often the pet people leave at home with a sitter dropping in, and that is a different ledger with different questions in it. Price it next door and put the two totals side by side before you decide the cat is coming.

Frequently asked questions

How much does it cost to fly a cat?
It comes down to the airline's in-cabin pet fee, how many flights are in the itinerary, whether the carrier costs you a checked bag, and what your vet charges for an exam and a health certificate. At our defaults it is $760 for a nonstop round trip on a two-week holiday, and only $250 of that is the pet fee itself. Put your own quotes in above, because ours are placeholders and yours are real.
Why is the total so much higher than the airline's pet fee?
Three reasons, and none of them are on the fee page. The fee is charged per flight, so a round trip pays it twice and a connection each way pays it four times. The carrier may take the space your carry-on would have used, which turns a bag you would have carried on into a checked bag, priced per flight the same way. And the vet exam and certificate sit outside the airline entirely. At our defaults the pet fee is $250 of a $760 total.
Does a cat carrier count as my carry-on bag?
That is set by the airline, and it is the single most useful question to ask when you ring to book the cat on. The carrier goes in the space under the seat in front of you, which is the space a carry-on would otherwise use, so some airlines treat it as your allowance and some do not. If yours does, and you then check a bag you would have carried on, that fee is charged on every flight in the itinerary, which at our defaults is $80 on a nonstop round trip. If yours does not, put a zero in the box and the line disappears.
Do I need two health certificates for a round trip?
You do if the trip is longer than the certificate's window. The certificate is written after an exam and is good for a stated period, so if it lapses while you are away, the return leg needs a fresh exam bought at your destination from a vet you have never met. That is our default case and it is the second $165 on the ledger. Set the window box from the rules for your actual route rather than from our placeholder, and check whether your usual vet is accredited to write one at all, because that is a question better asked three weeks out than three days out.
