Airline Approved Dog Crates: IATA Requirements to Know

Start with your airline and route

An airline approved dog crate is not one universal product. Each airline publishes its own pet travel policy, and the rules can differ by route, aircraft type, and whether the dog flies in the cabin, as checked baggage, or as cargo. For most dogs traveling in the hold, carriers use the International Air Transport Association (IATA) Live Animals Regulations as the baseline, so an IATA-style hard kennel is the safest place to start.

Dogs are one of the animals that the USDA Animal and Plant Health Inspection Service (APHIS) lists as pets that qualify for pet travel requirements. That means the process for a dog is different from livestock or poultry rules. Before you choose a crate, ask the airline for its current pet policy, then check the entry requirements for your destination. APHIS advises contacting a USDA-accredited veterinarian as soon as you decide to travel, because that veterinarian can tell you what vaccinations, tests, treatments, and health certificates your destination country requires.

Plan ahead. The paperwork and crate checks can take longer than expected, especially for international trips, so start the process well before your departure date.

Give your dog enough room to stand, turn, and lie down

The most common airline crate rule is about space. Your dog should be able to stand at full height, turn around, and lie down in a natural position. The crate should be long enough for your dog to stretch out, and tall enough that the ears or head do not press against the top. Measure your dog before you shop, because an oversized crate can be too large for the airline's cargo space and an undersized crate can be unsafe. Use a guide to measuring your dog and a crate size chart as a starting point, and remember that the interior space matters most for comfort while the exterior dimensions matter for the airplane.

For airline travel, hard-sided kennels are usually the accepted style for checked baggage or cargo. Soft carriers may be allowed for small dogs in the cabin, but only if the airline permits it and the carrier fits under the seat. If your dog flies in the hold, choose a hard-sided kennel that meets IATA-style construction and dimension rules. Compare the exterior dimensions of a candidate kennel with the airline's allowable size limits before you book.

When checking dimensions, consider both the interior room for your dog and the exterior size that airline staff will measure. The interior versus exterior crate dimensions guide explains why those two numbers can be very different.

Ventilation and materials for a safe flight

IATA-style kennels are built with ventilation openings so your dog gets enough air. Look for a crate with venting on opposite sides, and avoid blocking the openings with labels, bags, or straps. The kennel should also be made from rigid material that can withstand handling in the cargo hold. Wire crates and folding soft crates are rarely accepted for cargo because they do not offer the same protection.

The dog crate ventilation guide explains how airflow affects your dog's comfort, and the dog crate materials comparison can help you understand the differences between plastic, metal, and soft-sided crates. For air travel, a rigid plastic kennel is the most common choice because it is sturdy, cleanable, and easy for ground handlers to move.

Hardware, locks, and escape prevention

Airlines look for a door that locks securely. The latch should not pop open during handling, and the door hinge should be strong enough to resist pressure from a nervous dog. If the crate has small plastic clips, consider replacing them with stronger hardware before the flight. Many owners use metal bolts, washers, and zip ties to reinforce the door, but check the airline's policy before adding anything that ground staff may need to remove.

Escaping is a real safety risk during air travel. The ASPCA notes that dogs with separation anxiety may try to escape from confinement, and those escape attempts can cause self-injury. A dog who is anxious about being away from you may scratch, chew, or push at the door. Choose a crate with sturdy door construction and introduce the crate long before the flight so your dog does not associate it with stress. Review the dog crate latch types guide and the dog crate safety checklist before you finalize your setup.

The ASPCA also lists a training crate as an ideal place for a dog to rest, with clean bedding inside. Start using the crate at home as a positive space, then take short practice sessions so your dog is comfortable being inside. For a dog that is determined to get out, look at escape-proof dog crates and heavy duty dog crates with reinforced locks.

Labeling and paperwork for the trip

Most airlines require a live animal label on the crate, usually attached near the top or on the side where handlers can see it. The label should include your dog's name, your contact information, and sometimes the airline's air waybill number. You may also need arrows or the words This Side Up to show the correct orientation. The airline or your ticket desk will tell you exactly which labels are required.

Paperwork is just as important as the crate. For international travel, the process starts with a USDA-accredited veterinarian. APHIS says the veterinarian will help determine your destination country's pet entry requirements and assist with a USDA-endorsed health certificate. If your dog is returning to the United States, check the CDC's current dog import rules, including any rabies vaccination documentation your dog may need.

The CDC also encourages routine veterinary care and good hygiene around animals. After the flight, clean the crate and wash your hands after handling your dog, its food, waste, or supplies. This reduces the risk of spreading germs and helps keep both you and your dog healthy.

What to pick for your use

Questions

Does my dog need an IATA-approved crate?

Most airlines that carry dogs in the cargo hold expect the crate to follow IATA Live Animals Regulations. The airline's pet policy will say exactly which style and size it accepts. Confirm your route and aircraft type before buying or borrowing a crate.

Can I use a soft crate or wire crate for air travel?

Soft carriers may work for small dogs in the cabin if the airline allows it and the carrier fits under the seat. For dogs in checked baggage or cargo, airlines usually require a hard-sided kennel. Wire crates are generally not accepted because they do not provide the same protection during handling.

How do I know what size airline crate my dog needs?

Measure your dog from nose to base of tail, from floor to top of head, and across the shoulders while standing. Choose a kennel that lets the dog stand, turn around, and lie down flat. Check the kennel's exterior dimensions against the airline's cargo limits.

What paperwork does my dog need for air travel?

For international travel, contact a USDA-accredited veterinarian early. APHIS says they will help you meet the destination country's requirements and can prepare a USDA-endorsed health certificate. If your dog returns to the United States, also check CDC dog import requirements.

How can I help my dog stay calm in a crate during a flight?

Start crate training well before the trip so the crate feels familiar. The ASPCA notes that escape attempts and destructive behavior can be signs of separation anxiety, so practice leaving your dog in the crate for short periods. Give your dog a safe chew or a familiar item only if the airline allows items inside the kennel.
