How much does it cost to fly a cat or dog in the cabin?
$35–$150 each way in airline fees, across the 25 airlines that publish a plain US-dollar in-cabin pet fee — cats and dogs pay the same published fee. A round trip is two fees, so budget roughly double, plus a carrier that actually fits your airline's under-seat limit (some airlines ban cabin pets outright; check yours below).

What else to budget
The airline fee is only part of the cost. You also need a carrier that fits your specific airline's published under-seat limit — see the size and weight columns above, or run your airline through the fit matcher. On international trips, add a vet health certificate; we don't track carrier retail prices or vet costs here, so neither is estimated.

How much does it cost to bring a cat or dog on a plane?
In the cabin, $35–$150 each way in airline fees across the 25 airlines that publish a plain US-dollar fee, from our airline-by-airline index below. Cats and dogs pay the same published fee. A round trip is two fees, so budget roughly double, plus a carrier that fits your airline's published under-seat limit.
How much does it cost to fly a pet in general?
For an in-cabin pet, the airline fee itself runs $35–$150 each way. On top of that, budget for a carrier that fits your airline's published size limit (see the table below) and, on international trips, a vet health certificate — neither is priced here because we do not track carrier retail prices or vet fees.
Is the cost the same for every airline?
No — published in-cabin pet fees range 4.3× from the cheapest to the most expensive airline we track, and a handful of airlines ban cabin pets outright. Check your specific airline in the table below; airlines change fees without notice.
