When it comes to international pet relocation or moving abroad with dogs and cats, selecting the right pet carrier is crucial to ensure the safety and comfort of your pet during the flight. Additionally, to transport your pet in the cargo hold of an airplane, it is mandatory that the carrier complies with the regulations set by the International Air Transport Association (IATA).
In this article, we’ll explain in detail the key features that an IATA-approved carrier must have, as well as the correct measurements to ensure that your pet travels as comfortably as possible.
A pet carrier for air travel must comply with IATA regulations, which are essential for international flights. If the carrier does not meet these standards, the airline may refuse to allow your pet to board, potentially delaying your plans to fly with your pet.

Door hinges: The door hinges must protrude at least 1.6 cm above and below the edge of the door to reinforce the carrier’s security.
Choosing the correct carrier size is crucial to ensure your pet’s comfort during international air travel. Below, we explain how to measure your pet to select the right carrier, following IATA’s guidelines.

Height (B): Measure from the ground to the top of your pet's paws.
Total height (C): Measure your pet in its natural standing position, from the ground to the top of the ears or head.
The basic formula to calculate the appropriate carrier size is:
Carrier height: Equal to the pet’s total height (C).
Measure while standing: Measure your pet’s total length when standing upright.
Add extra space: Add approximately 10 cm to the obtained measurements to ensure the carrier is not too tight.
Once you have the correct measurements, look for a kennel or pet carrier that meets these criteria and is IATA-certified. This will ensure your pet can fly safely in the cargo hold.
