Cabin Pet Policy: What You Need to Know to Fly with Your Dog

Planning a trip and want your dog on the plane with you? Most airlines let small dogs, cats, and other pets sit in the cabin, but each carrier has its own rules. Knowing the basics before you book can save you time, money, and a lot of stress.

Size and Weight Limits

Almost every airline sets a maximum weight for cabin pets, usually between 5 kg (11 lb) and 8 kg (18 lb). The pet’s carrier must also fit under the seat in front of you. A common rule is that the carrier’s dimensions can’t exceed about 45 cm × 30 cm × 20 cm (18 in × 12 in × 8 in). If your dog is a tiny breed like a Chihuahua or a miniature dachshund, you’ll likely meet these limits. Larger dogs often have to travel in the cargo hold, even if they’re well‑behaved.

Booking Your Pet

Call the airline as soon as you know your travel dates. Some carriers let you add a pet online, but most require a phone reservation. You’ll pay a fee—usually between £25 and £60 each way. Keep in mind that airlines only allow a certain number of pets per flight, so the earlier you book, the better.

When you book, ask for a pet confirmation number. This is proof that your dog has a seat in the cabin and can help avoid problems at check‑in.

Carrier Choice and Comfort

Invest in a carrier that is airline‑approved, well‑ventilated, and sturdy. Line the bottom with a soft blanket and a familiar toy to calm your dog. Avoid feeding a big meal right before the flight; a light snack a couple of hours earlier works best. Offer water right up until you board, then another sip after take‑off and before landing if possible.

Place a label on the carrier with your name, phone number, and destination address. Some owners also add a vapor‑proof bag with a copy of the pet’s health certificate—many airlines ask for it at the gate.

Health Docs and Safety Checks

Most airlines require a recent health certificate issued by a vet within 10 days of travel. The certificate should confirm your dog is up‑to‑date on vaccinations and fit to fly. If you’re traveling internationally, check the destination country’s entry rules; some need a rabies antibody test or a quarantine period.

Bring your dog’s microchip number and any medication they need. If your pet gets anxious, talk to your vet about safe calming options before the trip.

At the Airport

Arrive at least two hours early for domestic flights and three hours for international trips. When you get to security, you’ll need to take the carrier out of the bag and place it on the conveyor belt. Keep your dog inside the carrier while it goes through the scanner.

Once you’re past security, find a quiet spot near your gate to let your dog stretch a little. A short walk around the terminal can help release nerves before boarding.

During the Flight

When the plane doors close, tuck the carrier under the seat in front of you. Keep the carrier upright and avoid leaning on it. Talk to your dog in a calm voice; hearing your tone can be reassuring. If the flight gets bumpy, a small, snug carrier helps your dog feel more stable.

Most airlines prohibit opening the carrier during the flight, so plan any bathroom breaks beforehand. For short trips, a quick restroom trip before boarding usually does the trick.

After Landing

Once the plane lands and the seatbelt sign is off, wait for the crew’s cue before moving the carrier. Open the carrier slowly and let your dog exit at its own pace. Offer water and a chance to stretch before you head to baggage claim.

Following these steps makes the cabin pet experience smoother for you, your dog, and the airline staff. With the right preparation, you can enjoy the journey together and start your adventure on the right paw.
