If your pet is moving by air as excess baggage or cargo, the crate you put them in is regulated. Airlines worldwide reference a single global standard — the International Air Transport Association's Live Animals Regulations (IATA LAR) — and a crate that doesn't meet it can be refused at check-in or at the cargo terminal.
This guide explains what "IATA-compliant" actually means, the six standard crate sizes airlines work with, the compliance checklist most carriers apply, and the most common mistakes that cause crates to be rejected.
Quick summary
- •IATA-compliant—means the crate meets the construction, ventilation, and sizing rules in the IATA Live Animals Regulations — the global standard nearly every airline references.
- •Six standard crate sizes—used in the industry, labelled PP30 through PP80 — from Small to Giant. The right size for your pet depends on their length, height, and weight.
- •Hard-shelled—with a metal door, metal fasteners, ventilation on at least three sides, and a solid roof and floor. Soft-sided crates are not accepted for hold travel.
- •Stand fully, turn around comfortably, and lie down naturally—inside the crate — this is the underlying IATA fit principle.
- •PP80 / Giant—is the largest standard size. Pets exceeding it need a custom-built crate — typically arranged through one of our vetted relocation companies or a specialist crate manufacturer.
What "IATA-compliant" actually means
The International Air Transport Association publishes the Live Animals Regulations (IATA LAR) — a single set of rules covering how live animals can be transported by air. Almost every commercial airline operating internationally references these rules as the baseline standard for pet travel.
For pet owners, "IATA-compliant" means the crate meets specific construction and sizing rules:
- The crate is rigid (hard plastic or fibreglass — not soft-sided fabric)
- It has a single secure metal door (no plastic latches)
- It has a solid roof and floor (no collapsible designs)
- All fasteners are metal (no plastic nuts and bolts)
- Ventilation openings cover at least 16% of the crate's surface, on a minimum of three sides
- The pet inside can stand up fully without their head touching the roof, turn around comfortably, and lie down naturally
A crate that fails any of these checks can be refused at the airline's cargo or check-in counter. Refusal at this stage means a missed flight, rebooking fees, and in some cases boarding charges while a compliant crate is sourced.
The six standard IATA crate sizes
Crates are manufactured in six standard sizes, labelled PP30 (smallest) through PP80 (largest). Most airlines and pet retailers refer to crates by these codes, and the Furs Class Travel platform uses the same naming so that what the free travel planner returns matches what you'll find in shops and on airline cargo websites.
| Name | IATA code | Internal dimensions | Weight ceiling |
|---|---|---|---|
| Small | PP30 | 54 × 41 × 38 cm | 2.5 kg |
| Medium | PP40 | 69 × 51 × 49 cm | 5 kg |
| Intermediate | PP50 | 82 × 56 × 59 cm | 7 kg |
| Large | PP60 | 82 × 61 × 66 cm | 10 kg |
| Extra Large | PP70 | 102 × 69 × 77 cm | 12 kg |
| Giant | PP80 | 122 × 82 × 89 cm | 19 kg |
The weight ceilings are guidelines — actual fit depends on your pet's body shape, not just weight. A long, narrow dog and a short, stocky dog of the same weight may need different sizes.
How to size a crate for your pet
The IATA fit principle has three checks, and your pet must pass all of them.
Standing clearance
With your pet standing inside the crate, there should be a clear gap between the top of their head (or their ear tips, if they stand upright) and the crate roof. A pet whose ears or skull touch the roof is in a crate that fails compliance.
Turning space
Your pet should be able to turn 360 degrees inside the crate without their body touching the walls or door. If they have to squeeze or contort to turn, the crate is too small.
Natural resting position
Your pet should be able to lie down in their normal sleeping position — stretched out or curled — without their body pressed against the crate sides.
The two measurements you actually need
To work out which size you need, take two measurements:
- Length: from the tip of your pet's nose to the base of their tail, while standing
- Height: from the floor to the top of their head (or ear tips, if upright), while standing
Match these against the six standard sizes above, or use the free travel planner to get the correct IATA bucket automatically.
Crate compliance checklist
This is the same checklist your pet travel plan returns — give it to your retailer when buying a crate, or use it to check a crate you already own.
- ✓≥ 16% open ventilation on at least 3 sides
- ✓Spring-loaded metal door — no plastic latches
- ✓Metal nuts and bolts only — no plastic fasteners
- ✓Affix "Live Animal" stickers to all 4 sides of the crate
- ✓Two clip-on bowls (one food, one water) attached inside the crate door
- ✓Solid roof and floor — no collapsible or soft-sided crates for cargo
Any crate that fails one of these points risks being refused at the cargo terminal. The metal-fastener rule in particular is the one most people miss — many off-the-shelf "airline-approved" crates ship with plastic nuts that need to be replaced before travel.
What to put inside the crate on flight day
Once the crate itself is compliant, the inside needs to be prepared correctly:
- Water bottle attached to the outside of the crate door
- Food in a ziplock bag taped to the top of the crate
- Absorbent pee pads on the crate floor
- A familiar blanket or worn shirt at the back for comfort
- Crate door secured with zip ties (additional to the metal latch)
- No loose toys inside the crate
Loose items, hard toys, and bedding that shifts can become hazards mid-flight. Less inside the crate is safer than more.
Where to buy IATA-compliant crates in the UAE
IATA-compliant crates are widely available in the UAE — major pet retailers in Dubai and Abu Dhabi stock the standard six sizes (PP30 through PP80). For most owners, a standard off-the-shelf crate from a reputable retailer is sufficient, provided you check it against the compliance checklist above before flight day.
If your pet exceeds the PP80 (Giant) size, you'll need a custom-built crate. These are typically arranged through specialist crate manufacturers or one of our vetted relocation companies. Use the free travel planner to get matched on supported routes.
Crate training before flight day
Buying the crate is only half the work. Pets that have not spent time in a crate before flight day are more stressed during travel, more likely to vocalise during transit, and more likely to refuse food and water.
A simple acclimatisation routine over 2 to 4 weeks before the flight makes a meaningful difference:
- Place the assembled crate in a familiar part of your home, with the door open
- Feed your pet's regular meals inside the crate, starting with the bowl just inside the door and gradually moving it to the back
- Add a familiar blanket or worn shirt for scent association
- Once your pet enters voluntarily, start closing the door for short periods — first 30 seconds, building up to several hours
- Avoid using the crate as a punishment space at any point
Pets that have been crate-trained typically settle within an hour of departure and rest for most of the flight. Pets that have not are more likely to remain anxious throughout.
Common mistakes
"My dog fits, so the crate is the right size."
Reality: Fitting in the crate isn't the test. Your pet has to be able to stand fully (head clearance), turn around 360 degrees, and lie down naturally. A crate that looks like a snug fit is usually too small for IATA compliance.
"The pet shop said it's airline-approved."
Reality: "Airline-approved" is not a regulated term. Some retailers use it loosely. The actual standard is IATA LAR — and the compliance checklist above is what airlines check at the counter. If a crate fails the checklist, "airline-approved" labelling on the box doesn't override the refusal.
"I'll buy the crate the week before the flight."
Reality: Two problems. First, the standard sizes can sell out at popular retailers in summer and around major holidays. Second, your pet won't have time to acclimatise — which makes the journey significantly harder for them. Buying the crate 3 to 4 weeks ahead solves both.
"The plastic nuts and bolts are fine."
Reality: Most off-the-shelf crates ship with plastic fasteners. These do not meet IATA requirements. The fix is straightforward — replace the plastic nuts and bolts with metal equivalents, available at any hardware store — but it has to be done before flight day.
"I'll save space with a soft-sided crate."
Reality: Soft-sided crates are accepted for in-cabin travel only (the small carriers that fit under an aircraft seat). For excess baggage or cargo, the crate must be rigid with a solid roof, floor, and walls.
"My dog is too big for any standard crate."
Reality: Pets exceeding the PP80 (Giant) size need a custom-built crate. This is not unusual — many large breeds (Mastiffs, Great Danes, Saint Bernards) require custom crates. Allow extra lead time, as custom builds take 2 to 4 weeks to manufacture.
