Why Travel Crates Matter for International Pet Relocation

International airlines follow strict regulations for pet travel crates to ensure:

  • Your pet can stand, turn around, and lie down comfortably
  • Proper airflow and ventilation during flight
  • Structural safety during handling and transport

Using the wrong crate size can result in:

  • Airline refusal at check-in
  • Travel delays
  • Stress or discomfort for your pet

That’s why crate selection is a critical part of the relocation process.

What Type of Crate Is Required for International Pet Travel?

Most international flights require an IATA-compliant hard-sided travel crate.

These crates typically include:

  • Rigid plastic or fiberglass construction
  • Ventilation on all four sides
  • Secure metal door and locking system
  • Leak-proof base
  • Proper labeling and live-animal stickers

Soft-sided carriers are not permitted for cargo or checked-baggage international travel.

How Airline Crate Sizing Works

Airlines do not size crates based on your pet’s weight alone. Instead, crate size is determined by your pet’s physical measurements.

Your pet must be able to:

  • Stand upright without touching the top
  • Turn around comfortably
  • Lie down naturally

If the crate is too small, airlines may deny boarding – even if your pet fits inside.

How to Measure Your Pet for a Travel Crate: Step-by-Step Measuring Guide

You will need a measuring tape and your pet standing naturally.

  1. Length (A → B)

Measure from:

  • The tip of your pet’s nose
  • To the base of their tail (not the end of the tail)
  1. Height (C → D)

Measure from:

  • The floor
  • To the top of your pet’s head or the tip of the ears (whichever is higher)
  1. Width
  • Measure your pet at the widest point of the body (usually shoulders or hips).

Choosing the Correct Crate Size

Once measurements are taken:

  • The crate’s internal length must exceed your pet’s body length
  • The internal height must exceed standing height
  • Width must allow your pet to turn comfortably

Airlines often require a crate one size larger than what pet owners expect.

Common Travel Crate Mistakes to Avoid

  • Choosing a crate based only on weight
  • Buying the smallest crate your pet “fits” into
  • Waiting until the last minute to purchase a crate
  • Not crate-training before travel
  • Using non-IATA or airline-incompatible crates

These mistakes can result in travel delays or denied boarding.

Crate Training Before International Travel

We strongly recommend introducing your pet to their crate weeks before travel.

Helpful tips:

  • Leave the crate open at home
  • Add familiar bedding or toys
  • Offer treats and meals inside the crate
  • Gradually increase time spent inside

Crate training helps reduce anxiety and makes travel far less stressful.

Frequently Asked Questions
About Pet Travel Crates

Soft-sided carriers are not permitted for international cargo or checked-baggage travel.

Your pet’s crate must be sized based on physical measurements, not weight alone. When standing naturally, your pet should not touch the top of the crate and should be able to turn around and lie down without restriction.
