What Size Pet Carrier is Allowed on Airlines? A Guide to Pet Carrier Dimensions

Understanding Airline Pet Carrier Size Requirements

If you plan on traveling with your furry friend by air, one of the most important things to understand is airline pet carrier size restrictions. Getting the right sized carrier is essential for your pet’s safety and comfort during the journey. In this article, I’ll address some of the most common questions pet owners have when figuring out pet carrier dimensions.

Why do airlines restrict pet carrier sizes?

There are a few key reasons why airlines set maximum carrier size limits:

1. Safety – Larger carriers pose more risks if they shift or fall during takeoff/landing. The cabin needs to adhere to strict weight and balance guidelines.
2. Space – Plane cabins have limited under-seat storage room. Oversized carriers won’t fit properly and could block emergency exits.
3. Fairness – Restricting sizes prevents some passengers from taking up an unreasonable amount of cargo space with their pet.

In the end, it comes down to safely transporting as many pets as possible within the physical constraints of the aircraft.

How can I find my airline’s pet carrier size rules?

Most major carriers publicly list their pet carrier dimensional policies on their websites. However, it’s always a good idea to double check with the airline before your trip, as rules can occasionally change. You can typically find pet policies under the “Special Assistance” or “Traveling with Pets” sections of their site.

Alternatives for finding sizes include calling the airline’s reservations line, searching online travel forums, or looking at the carrier manufacturer’s listings of airline-approved dimensions. Confirming the sizes ahead of time prevents disappointment at the airport.

What are some typical size limits?

While specifics vary slightly by airline, here are some common maximum pet carrier dimensional standards:

• Length – Generally 18-22 inches
• Width – 10-14 inches
• Height – 9-13 inches

Keep in mind size is measured point-to-point, not factoring in things like handles that may extend beyond the carrier perimeter. It’s also best to leave extra room and not max out the limits if possible.

How can I determine the right-sized carrier for my pet?

When selecting a carrier, think about comfort as much as compliance with airline rules. Here are some key points:

1. Measure your pet – Provide at least 3-4 inches of extra space around your pet’s body in all directions.
2. Consider growth – Choose a carrier your pet can grow into if needed versus its current size alone.
3. Standing vs. lying – Some pets prefer standing, others like to fully lie down. Find the proper stance.
4. Visual comfort – Mesh windows help pets see their environment and anxious owners can still check in.

With sizing, it’s best to err on the side of more space versus minimum allowances. A happy pet will make for a smoother travel experience.

What about airline pet requirements beyond size?

Carriers must meet additional criteria:

• Be rigid/won’t collapse or break open. Soft-sided carriers don’t usually qualify.
• Have proper ventilation – Never leave openings that could allow escape or injury.
• Have a waterproof bottom – No urine or mess leakage mid-flight.
• Fit under the seat – It attaches securely and never blocks exits/aisles.

Most airlines also expect your pet to remain quiet, calm and not need to relieve itself for extended periods.

Any tips for preparing pets mentally and physically?

Introducing your pet to their carrier well ahead of time goes a long way in reducing anxiety. Things that may help include:

1. Positive reinforcement – Feed meals inside the carrier with doors open and closed.
2. Gradual desensitization – Give treats when near it at first, then going inside.
3. Make it cozy – Provide toys, blankets that smell like home.
4. Practice travel – Do test runs in car for short distances before the big day.
5. Sedation OK if needed – Discuss this option with your vet if flying will be highly stressful.

A calm, well-trained pet makes airline travel much less overwhelming on the whole.

Will I encounter any other pet travel hassles or restrictions?

Other considerations include:

• Some countries or connecting carriers have entry requirements beyond airline rules.
• Certain breeds may have transport limitations based on past incidents.
• Costs to fly pets are high – Expect fees for tickets, carriers and check-in.
• Not all legs or carriers allow onboard – Check ahead if advance pet cargo is needed.

Taking the time to thoroughly research all policies will smooth out any bumps in the pet travel process. Hopefully this helps shed some light on carrier size questions many pet owners have to get Fido or Fluffy home safely!

FAQ

1. What size pet carrier do I need for my airplane travel?

   Most airlines allow pet carriers that are not larger than 18 inches by 14 inches by 9 inches (45cm x 35cm x 23cm). This size fits under the seat in front of you. However, some smaller dogs and cats can get away with smaller carriers as well. Always check your airline’s policies.

2. Is a soft-sided carrier okay or do I need a hard-sided one?

   In general, either a soft or hard carrier is permitted as long as it fits within the size requirements. Hard carriers are a little more secure while soft carriers tend to be more comfortable for your pet. Whichever type you choose, make sure it’s well-ventilated and your pet has room to stand up and turn around.

3. Do I have to check my pet carrier as luggage?

   No, you are allowed to keep your pet carrier with you in the cabin as your carry-on item. Just be aware that some airlines may charge a fee if it takes up too much room under the seat. Checking it as luggage is usually a last resort since it subjects your pet to more stress without you there.

4. When booking my flight, do I need to specify I’m traveling with a pet?

   Yes, you will need to inform the airline at the time of booking if you wish to bring your pet on board in a carrier. Most require advance notice and payment of any applicable pet fees. Failure to disclose this could lead to denied boarding at check-in. It’s best to confirm pet policies beforehand so no surprises await you at the airport.

   

5. Do airline pet carriers need to be certified or labeled?

   Some major airlines require the use of carriers that are certified by the International Air Transport Association (IATA). These have passed certain safety tests. Even if not mandatory, it puts the crew at ease to see the IATA label stating your carrier is airline-approved. You can find these easily online or at pet stores. An IATA sticker or tag firmly attached helps avoid potential issues.

6. Can I use a blanket or toys in the carrier?

   As long as it doesn’t take up too much extra room, most airlines permit adding a few small comfort items inside the carrier such as a lightweight blanket, toy or two. No external accessories like collars, leashes or bowls are allowed to stay on for the flight itself. Focus more on your pet’s well-being and security over style or entertainment while traveling by plane.
