IATA-approved pet carrier
Flying with your pet requires meeting strict regulations, and the first step is having an IATA-approved pet carrier. Not every model on the market complies with IATA standards, which govern air transport of animals. Choosing correctly not only ensures your dog or cat can travel with you, but also that it does so safely and comfortably. Below, you will find a detailed guide to understand the required features, the carrier types available, practical travel tips, and purchase recommendations.

What is an airline-approved carrier and why do you need one?
An IATA-approved pet carrier is a container designed to transport pets in compliance with IATA (International Air Transport Association) requirements. This means it is built with suitable materials, dimensions, and safety systems so animals can travel in cabin or in the hold under international aviation rules.
Approval is not a luxury, but a safety guarantee. Every airline demands that the carrier meet these requirements to avoid risks during the flight. For example, a non-approved carrier could break, open accidentally, or fail to provide adequate ventilation. In addition, on long trips it is essential that the pet has enough room to stand, turn, and lie down comfortably.
In short, using an approved carrier is not only mandatory on most airlines, but also a sign of responsibility toward your dog’s or cat’s well-being.
IATA requirements for airline pet carriers
For a carrier to be accepted on an international flight, it must meet IATA’s requirements. These vary depending on whether the animal travels in cabin or in the hold. However, the main points to consider are the following:
- Sturdy material: the carrier must be made of rigid plastic, metal, or equivalent materials—never fabric or cardboard.
- Secure locking system: it must include a latch that prevents the pet from opening it from inside.
- Adequate ventilation: at least on three sides to ensure proper airflow.
- Leak-proof floor: prevents liquid spills and keeps the carrier clean and safe.
- Correct dimensions: the animal must be able to stand, turn around, and lie down normally.
For cabin travel, most airlines allow soft carriers provided they are flexible, lightweight, and fit under the seat. For the hold, a rigid, approved carrier is always required.


Tips to prepare your pet before the flight
Air travel can be stressful for your pet, so good preparation is essential. Here are some practical tips:
- Get your pet used to the carrier: place it at home days before the trip with blankets and toys so it becomes a safe place.
- Exercise your pet before flying: a good walk or play session will help it travel more relaxed.
- Avoid heavy meals: ideally, do not feed your pet in the 3–4 hours prior to the flight to prevent nausea or vomiting.
- Clear identification: attach a tag with your contact details and your pet’s information to the carrier.
- Visit the vet: ensure vaccinations are up to date and request a health certificate if the airline requires it.
One important note: never medicate your pet without veterinary advice. Some sedatives can be dangerous during pressure changes in flight.

Common mistakes when choosing an airline carrier
Many owners make mistakes when selecting a carrier for air travel. Knowing them will help you avoid issues:
- Buying a carrier that is too small: comfort is crucial. A dog or cat that cannot move freely will be stressed and may be denied boarding.
- Choosing non-approved models: some carriers are fine for car use but do not meet air regulations.
- Not checking airline requirements: each carrier has specific rules. Some limit cabin weight, others demand double locks for the hold.
- Not prepping the carrier’s interior: it is best to add an absorbent pad, a toy, and, on long routes, a water bowl designed for carriers.
- Trusting second-hand carriers without inspection: they may be damaged or fail to meet current standards.
A frequent error is assuming any rigid carrier will do. In reality, if it lacks required ventilation and locking systems, it can be rejected at the airport. Therefore, always check airline rules in advance and opt for models clearly marked as IATA-approved.
How to choose the best IATA-approved carrier for your pet
Selecting the right carrier depends on several factors: your pet’s size and weight, flight duration, and airline conditions. Here are key points to get it right:
- Correct size: measure your pet from nose to tail base and from floor to head. Add a few centimeters and choose a carrier that allows easy movement.
- Cabin or hold: if your pet weighs under 8 kg (carrier included), most airlines allow cabin travel. Above that, the pet must go in the hold.
- Material: rigid plastic carriers with a metal door are safest for the hold. For cabin, flexible soft-sided models with a rigid base are commonly accepted.
- Accessories: some approved carriers include water bowls, removable wheels, or reinforced locks. These details improve comfort.
- Brand and certification: check that the model explicitly states IATA approval and, if possible, look for reviews from other travelers.
Ultimately, your choice should balance safety, your pet’s comfort, and the airline’s requirements. It is not an impulse buy, but an investment in a stress-free trip.
Frequently asked questions about IATA-approved carriers
What does IATA-approved mean for a pet carrier?
It means the carrier meets the International Air Transport Association’s standards. These rules set the materials, dimensions, and safety systems a carrier must have to be accepted on commercial flights. An approved carrier helps your pet travel safely and prevents boarding refusals.
Can I take my dog in the cabin with an approved carrier?
Yes, as long as your pet meets the airline’s weight and size limits. Generally, the cap is 8 kg including the carrier. It must fit under the seat in front, so soft, flexible carriers are typically allowed—provided they are approved. Always check with your airline before flying.
What happens if my carrier is not approved?
If your carrier is not approved, the airline may refuse to board your pet. Even if allowed, the carrier might not provide adequate safety or ventilation. That is why you must verify IATA compliance and your airline’s specific requirements before buying.
What is the difference between a car carrier and an airline carrier?
Car carriers do not always meet air-travel standards. They may work for road trips but lack the ventilation, strength, and locking systems IATA requires. An airline-approved carrier is designed to withstand handling, pressure changes, and to guarantee the animal’s safety during flight.
How should I prepare the carrier for a long flight?
Set it up with an absorbent pad on the floor, a familiar toy for your pet, and, on very long flights, a bowl that attaches to the door. Also label the carrier with your contact details and add "live animal" tags. Never use sedatives without explicit veterinary guidance.
Can I rent an approved carrier at the airport?
Some international airports offer rental services, but it is not advisable. Your pet should get used to the carrier in advance, which is impossible if you rent on the day. You also risk the model not being accepted by your airline. It is better to buy your own and prepare it at home.
How much does an IATA-approved carrier cost?
Prices vary by size and materials. Small cabin carriers often range from €30 to €80, while large hold-approved models usually cost between €90 and €200. It may seem pricey, but remember it is about your pet’s safety and comfort in a demanding environment like an airplane.
