Airline-approved dog crates: what the IATA rules actually require

Updated: · Joan

Quick answer

For the hold, airlines apply the IATA Live Animals Regulations (Container Requirement 1): a rigid crate (hard plastic, wood or metal), solid roof, metal door, ventilation openings on at least three sides, nuts and bolts closing the two halves (not just clips), wheels removed or blocked, and a size that lets your dog stand upright, turn around and lie down naturally. 'IATA-approved' printed on the box is marketing, no crate is pre-approved: the airline checks the crate against the rules, with your dog inside it, at check-in.

TL;DR

  • No crate is 'IATA approved' from the factory: compliance is checked per flight, per dog, at the counter.
  • Measure the dog, not the crate aisle: height standing, length nose to tail base, plus room to sit upright without ears touching the roof.
  • Metal door, rigid shell, bolted halves, ventilation on 3 sides minimum (4 for many international routes).
  • Snub-nosed breeds need one size larger and many airlines refuse them in the hold entirely: check the embargo list first.
  • Water and food containers must be attached to the door and refillable from outside.

The rules below come from IATA's own Live Animals Regulations guidance and from the pet pages of the airlines themselves, linked at the end with the date we checked them. We deliberately do not list specific crate models with prices here: stock and prices rot fast, the rules do not. When we publish model comparisons they will carry their own dated price checks.

What the counter check actually looks at

1. Materials and structure

Rigid shell of hard plastic, wood, metal or similar. Two-piece plastic crates must be joined by nuts and bolts, not only the snap clips they ship with. The door must be metal, spring-locked, and impossible to open from inside. Roof solid: no skylights or door on top.

2. Ventilation

Openings on at least three sides for domestic standards, four for most international handling, with the openings small enough that no nose or paw fits through.

3. Size, measured on your dog

The dog must stand with head in natural position without touching the roof, turn around, and lie down stretched. Airlines use your dog's measurements (height standing, length nose to tail base, shoulder width) against the crate's internal dimensions. If in doubt between two sizes, larger.

4. The details that get crates rejected

Wheels not removed or taped, no absorbent bedding, bowls missing or not refillable from outside, 'Live Animal' labels missing (airlines usually provide them), and crates with top-opening doors. Bring cable ties and a marker: counters ask for odd fixes and it is better to fix than rebook.

Cabin is a different world

None of this applies to in-cabin soft carriers, which follow each airline's own dimensions. That comparison is its own guide on this site.

Frequently asked questions

Is there an official list of IATA-approved crates?

No. IATA publishes container requirements, not approved product lists. Any 'IATA approved' badge on a box means 'designed to comply', and the airline still verifies at check-in.

Can my dog's crate have wheels?

Crates often ship with wheels, but for flying they must be removed or immobilized. Counters carry tape, but do it at home.

How do I measure my dog for the crate?

Three numbers standing: height floor to head (or ear tips for erect-eared breeds), length nose to base of tail, and shoulder width. The crate's internal height and length must exceed them with margin to sit and turn.

Are soft-sided crates ever allowed in the hold?

No. Soft carriers are cabin-only. The hold requires rigid construction.

Why do airlines refuse snub-nosed breeds in the hold?

Brachycephalic dogs have elevated breathing risk under heat and stress, and several airlines embargo them in cargo partially or by season. Check your airline's breed list before buying anything.

Does the crate need food and water bowls even for a short flight?

Yes, attached to the door and refillable from outside, regardless of flight length: delays are exactly the scenario the rule exists for.
