What are airline-approved pet carriers?

'DEFRA-approved pet carriers must meet specific size requirements to ensure the safety and comfort of pets during travel. While the exact dimensions vary from passenger airline to passenger airline, here are some general guidelines:

Carrier Dimensions: Most approved carriers have dimensions that allow them to fit comfortably under an airliner seat. Each aircraft’s seats differ from one another so you should obtain this information from your chosen airline. However, we took the dimensions of the under-seat spaces from each U.K. based passenger airliner and came up with the average:

Width: 47.89 cm
Height: 34.56 cm
Depth: 20.22 cm

Pet Weight Limit: The weight limit for pets in the cabin typically ranges from 6 kg to 8 kg (approximately 13 lbs to 18 lbs).'

Pet Carriers for Vet Visits - Safe, Comfortable Trip for your Pet

To determine the minimum inner dimensions of the air-travel crate, such as the Henry Wag Wheeled Airline-Approved Pet Crate, you must measure your pet while they are standing naturally and use these four metrics:

A is the length of the animal from the tip of the nose to the base of the tail.
B is the height from the ground to the elbow joint.
C is the width across the widest point of the shoulders.
D is the height of the animal in a natural standing position from the floor to the top of the head or tip of the ears, whichever is higher.

Calculating the Dimensions

Minimum Length: A + ½B (The length of the animal plus half the length of its leg).
Minimum Width: C x 2 (Twice the width of the animal’s shoulders).
Minimum Height: D (The total standing height of the pet; their head or ears must not touch the roof).


Note: For snub-nosed breeds, many airlines require you to buy a crate that is one size larger than these calculations to ensure extra airflow.
