Flying with a pet in the cabin requires careful planning. Every airline has specific rules for carrier dimensions, fees, and the number of pets allowed per flight. This guide covers the key steps to prepare yourself and your pet for a smooth journey, from choosing the right carrier to navigating airport security.
Understanding Airline Requirements
Before you book a ticket, you must understand the airline’s pet policy. Rules vary significantly between carriers and even between different aircraft types operated by the same airline. Always check the airline’s official website for the most current rules before you make a reservation.
Size and Weight Limits. The carrier must fit completely under the seat in front of you. Airlines publish maximum carrier dimensions, and soft-sided carriers are almost always required because they can compress slightly to fit. Some airlines also have a combined weight limit for the pet and carrier, while others only restrict the carrier size.
Breed Restrictions. Certain brachycephalic (short-nosed) breeds, such as bulldogs, pugs, and some Persian cats, may be restricted due to potential breathing difficulties at altitude. Check this carefully if you own a snub-nosed breed.
Number of Pets. Most airlines limit the number of pets in the cabin per flight, often to just two or three. This makes it essential to book your pet’s spot as early as possible, ideally immediately after purchasing your own ticket.
Fees. Airlines charge a non-refundable fee for cabin pet travel. This fee is typically paid at check-in or when you add the pet to your reservation.
Destination Requirements. If you are traveling to a different state or country, check the official animal health requirements for that destination. Your veterinarian and the destination’s department of agriculture are good resources. For a broader overview of travel gear, check out our Pet Travel Buying Guides.

Choosing the Right Carrier
Your pet’s carrier is the most important piece of gear for cabin travel. It must meet airline specifications and be comfortable for your pet.
Soft-Sided Design. A soft-sided carrier is almost always required. It should be well-ventilated on at least two or three sides and have a sturdy, leak-proof bottom. Look for a carrier that is sturdy enough to hold its shape but flexible enough to fit under the seat.
Proper Fit. The carrier must be large enough for your pet to stand, turn around, and lie down, yet small enough to fit under the seat. Measure your pet and compare the dimensions to the airline’s requirements.
Getting Your Pet Used to the Carrier. Introduce the carrier well before your trip. Leave it out in your home with the door open. Place treats, toys, and familiar bedding inside so your pet associates it with positive experiences. You can gradually encourage your pet to spend more time inside. Our Pet Buying Guides can help you compare features of different carrier types.
Preparing Your Pet and Documents
Health Certificates. Some airlines and destinations require a certificate of veterinary inspection (health certificate) issued within a specific window before travel. Your veterinarian can provide this after a checkup. Ensure your pet’s rabies vaccination and other routine vaccines are up to date.
Identification. Make sure your pet has a collar with an ID tag that includes your contact information. Ensure their microchip registration is current.
Food and Water Timing. Feed your pet a light meal a few hours before the flight to prevent an upset stomach. Provide water up until you leave for the airport. You can offer small amounts of water during layovers.
Sedatives. Never give your pet sedatives or calming medications unless specifically prescribed by your veterinarian. Sedatives can affect your pet’s balance and breathing at altitude, which can be dangerous.

At the Airport and Through Security
Check-In. When you check in, inform the agent that you are traveling with a pet in the cabin. You will likely need to pay the pet fee at this point.
Security Screening. The Transportation Security Administration (TSA) requires that you remove your pet from the carrier before the carrier goes through the X-ray machine. You will carry your pet through the metal detector while holding them securely on a leash. The carrier must be empty when it goes through the scanner. Practice this process at home if your pet is nervous.
Absorbent Pads. Line the carrier with an absorbent pad in case of accidents. Bring several extras in a small bag for layovers.
Boarding and In-Flight Tips
Staying Calm. Your pet will pick up on your energy. Speak in a calm, reassuring voice. A familiar blanket or toy inside the carrier can help.
On the Plane. Place the carrier under the seat in front of you immediately. Keep the carrier zipped up for the duration of the flight. Resist the urge to take your pet out, as this is against airline rules and can be unsafe.
During the Flight. During turbulence, a secured carrier is the safest place for your pet. If your pet seems anxious, you can quietly talk to them through the mesh.
Common Mistakes and Troubleshooting
Not Booking the Pet Early. Waiting until the last minute often results in no available pet spots on the flight.
Assuming the Carrier Fits. Always check the under-seat dimensions for the specific aircraft you will be flying on. Not all seats are the same size.
Skipping Carrier Training. A pet that has never seen a carrier before will be much more stressed on travel day.
Overfeeding Before the Flight. A full stomach can lead to motion sickness or discomfort.
Forgetting Destination Rules. Some states and countries have strict quarantine or vaccination requirements.
Troubleshooting a Nervous Pet. If your pet shows signs of extreme stress, consult your veterinarian before the trip. They may recommend a behavior modification plan or, in rare cases, a prescription medication specifically for travel.
Troubleshooting Accidents. Pack extra absorbent pads and a small bag for soiled ones. You can discreetly replace the pad in a restroom during a layover.
FAQ
Can my pet sit on my lap during the flight?
No, pets must remain inside their carrier, which must be stowed completely under the seat in front of you for the entire flight. Taking a pet out of the carrier is against airline rules.
What if my pet cries or barks during the flight?
Comfort them calmly through the carrier. Do not open the carrier. Often, the white noise of the plane helps them settle down. A familiar toy or blanket can also provide comfort.
Do I need a health certificate for my pet?
It depends on the airline and destination. Always check the specific requirements of your airline and the destination’s animal health authority. Your veterinarian can help you determine what is needed.
What about emotional support animals?
Most airlines no longer accept emotional support animals in the cabin. They are generally treated as pets and must follow the standard pet in cabin policy, or they travel as service animals if they meet specific training requirements defined by the Department of Transportation.
Flying with a pet in the cabin is entirely possible with thorough preparation. By understanding airline policies, choosing the right carrier, and getting your pet comfortable ahead of time, you can reduce stress for both of you. Always confirm the latest rules directly with your airline and consult your veterinarian for any health-related questions.
