Selecting the right travel kennel is one of the most important decisions you'll make when preparing your pet for international travel. A properly sized, IATA-compliant kennel helps keep your pet safe, comfortable, and secure throughout their journey while ensuring they meet airline and destination requirements.
With so many kennels advertised as "airline approved," it can be difficult to know which one is actually accepted by the airline. In reality, kennel requirements can vary between airlines, and choosing the wrong size or style could result in delays, additional expenses, or even your pet being denied travel.
Did you know? One of the most common reasons pets are delayed or denied travel is because their kennel doesn't meet airline or destination requirements. Taking the time to choose the right kennel can help prevent costly delays and unnecessary stress on travel day.
Measure Your Pet Before Purchasing a Kennel
Before purchasing a travel kennel, take accurate measurements of your pet. Choosing a kennel based on breed or weight alone can result in a crate that is too small or too large. Your pet should be able to:
- Stand naturally without their head or ears touching the top of the kennel
- Turn around comfortably
- Lie down in a natural resting position
- Sit comfortably without restriction
Using your pet's measurements rather than the kennel's advertised size is the best way to ensure a safe and comfortable fit.

Airline Requirements for Pet Travel Kennels
It's also important to make sure your kennel meets your airline's current pet travel requirements. In general, an acceptable travel kennel should include:
- Ventilation on all required sides for proper airflow
- For cats, openings on all sides of the crate cannot exceed 3/4 inch in diameter
- For dogs, openings on all sides of the crate cannot exceed 1 inch in diameter
- A secure, escape-resistant door with sturdy locking hardware
- Durable construction designed for air travel
- Adequate interior space based on your pet's measurements
Keep in mind that each airline may have additional requirements regarding kennel construction, hardware, ventilation, or accessories. Always verify your airline's guidelines before purchasing a kennel.
Preparing Your Kennel for Travel
Preparing your pet's kennel properly before travel is just as important as choosing the correct size. Taking the time to set up the kennel according to airline requirements can help ensure a smoother check-in process and keep your pet comfortable throughout the journey.
Before travel, make sure your kennel includes:
- Absorbent bedding or kennel liner
- Empty food and water dishes attached to the door
- Live Animal labels
- Identification labels
- Copies of travel documents in a waterproof pouch
- Familiar scent item for comfort
No matter where you acquire your pet's kennel, whether it's from World Pet Travel, purchased online, or custom-built, certain things remain the same. One such requirement is providing your pet with 1-2 inches of absorbent material on the kennel floor.
Certain items, such as excessive bedding, toys, harnesses, and treats, are not permitted inside the travel crate. Cups must be affixed to the door and be accessible from the outside.
GPS tracking devices like Apple AirTags or Samsung Smart Tags are banned by the airline as they pose a choking hazard and lithium battery risk.
Common Mistakes to Avoid
- Choosing a kennel based only on your pet's breed or weight.
- Assuming "airline approved" means every airline will accept the kennel.
- Waiting until the last minute to crate train your pet.
- Forgetting to check your airline's latest kennel requirements.
- Using an older, damaged, or improperly assembled kennel.
⚠️ "Airline Approved" Doesn't Always Mean Airline Compliant ⚠️
Many kennels are marketed as "airline approved," but that label can be misleading. Every airline has its own pet travel policies, and some destinations have additional import requirements. A kennel that is accepted by one airline may not meet the standards of another. Always verify your airline's current kennel requirements before purchasing or traveling.
