IATA dog crate for the aircraft hold: how to choose

“IATA approved” is not a product badge: IATA states that it does not certify or endorse commercial models. What matters is the actual crate, which the airline may reject at check-in.

The IATA internal-dimension formula

Minimum internal size

Length = A + ½B · width = C x 2 · height = D + bedding thickness. IATA calls for a 10% larger crate for snub-nosed breeds, but the airline may still prohibit them in the hold.

2026 IATA formula for calculating the internal length, width and height of a dog travel crate
These are internal measurements: A nose-tail, B ground-elbow, C shoulder width, D natural height.

Construction that passes inspection

The crate must be rigid, strong, escape-proof and leak-proof, with a waterproof floor and absorbent material. The door must close securely; the halves of a plastic crate must be fastened as the carrier requires. Full wire cages and oversized openings can cause rejection.

Ventilation, spacers and handles must remain clear when loaded near other items. Food and water bowls should be fixed and accessible from outside. Live-animal labels, names, contact details and instructions are added under airline rules.

Practical test before the airport

  1. The dog enters without bending head or ears.
  2. It can stand and sit naturally.
  3. It can turn without becoming stuck.
  4. It can lie down fully.
  5. The door does not open when pushed from inside.
  6. Bowls can be filled from outside.
