Flying with a Cat in the Cabin
6 min readSources checked
Airline and government rules change. Check your airline's current rules before you travel.
Quick answer
Reserve the cat's place before assuming the booking is finished. Airlines limit the number of cabin pets, and paying for your own ticket does not reserve space for the animal.
A cat in the cabin is two bookings, not one: your seat, and the animal's place, which is limited and sold separately. The rest is a carrier that satisfies two different tests at once, a checkpoint where the cat comes out of the bag, and entry rules at the destination that the airline does not decide.
Scope: Carrier fit, booking, Canadian security screening and the trip through the cabin with a cat. Airline examples are identified as such and should be rechecked before each journey. Destination entry rules are named but not listed country by country.
Part of: Flying with a Pet
What changes by airline
- How many cabin pets the airline allows on the flight
- The carrier dimensions, which can differ by aircraft and cabin
- Weight, age and route conditions
- The fee and the check-in method
- Whether a partner-operated segment accepts a cabin pet at all
General advice: applies wherever you fly
The carrier has to pass two tests
It must fit under the seat on the aircraft, and the cat must be able to stand, turn around and lie down inside it. A carrier that matches the published dimensions exactly can still be refused if it is too small for the animal in it.
Measure the carrier after it is assembled and filled with its normal pad. Flexible sides help only if the frame and the zippers still fit under the seat. Avoid a rigid bubble window or decorative structure that stops the bag from flexing where the airline expects it to.
General advice: applies wherever you fly
Before booking, ask every operating airline
Check the rule for the airline operating every flight, not only the one selling the ticket. A codeshare deserves particular attention, because the airline on the ticket may not accept a pet on a partner-operated segment.
Call before buying a fare that cannot be refunded, ask the agent to add the cat to the reservation, and ask for written confirmation.

Air Canada: a closed soft-sided carrier under the seat
Air Canada currently requires a flexible soft-sided carrier for cabin pets on its eligible flights, and its published dimensions vary by aircraft and cabin. It requires the animal to remain in the closed carrier under the seat, and says the cat must be able to stand, turn and lie down.
Those details show why measuring only the outside of the bag is not enough. They are Air Canada's current requirements, they can change, and they are not universal airline rules.

Prepare the cat, not just the bag
Let the cat spend time in the carrier well before the trip, and use it at home as a familiar resting place rather than bringing it out only for stressful journeys. Add an absorbent liner and carry a spare in a sealed bag.
Keep identification on the cat and on the carrier, and make sure the mobile number on it can be reached during the trip.
Discuss anxiety or motion sickness with a veterinarian. Do not give a sedative or any other medication because another traveller recommended it. The veterinarian who knows the cat decides whether medication is appropriate and how it should be used.

Canada: at the screening checkpoint
At a CATSA checkpoint the cat comes out of the carrier and the empty carrier is screened separately. Removable clothing or accessories come off, while a collar and harness may remain. Keep the cat close and under control.
If opening the carrier in the public checkpoint creates an escape risk, ask for a private search room before unzipping it. CATSA says that option may be offered, and it is a sensible request for an anxious or easily startled animal. Worth knowing: fit the harness before you reach the checkpoint, not in the line.

At the gate and on board
Arrive at the airline's required check-in time. Some carriers do not allow online or kiosk check-in with a cabin pet, because an agent needs to inspect the reservation and the carrier.
Keep the cat inside the closed carrier unless airline or security staff direct otherwise. The under-seat space is the cat's assigned location, so do not plan to use it for a second personal bag. Do not open the carrier to comfort the cat in flight: a calm voice and a hand resting on the outside are safer than an animal loose in an unfamiliar cabin.
Tell a flight attendant if the cat appears to be in distress, or if the carrier becomes soiled and you need help deciding where that can be handled. Do not take the cat into a lavatory without asking. The space is small, loud and easy to block during service.

Canada: the border is a separate decision
Cabin acceptance and border permission are not the same thing. The airline can accept the cat and the destination can still refuse entry if the paperwork is wrong.
The Canadian Food Inspection Agency advises checking the destination's import requirements as soon as travel details are known. Requirements can include vaccination, a health certificate, testing, medication or official endorsement completed within a specific window.
Check the return at the same time. A cat coming back to Canada is still subject to Canada's import rules, whatever the outbound country required.
