What is IATA LAR?

The IATA Live Animals Regulations bring together the standards used to help airlines, cargo teams, ground handlers and shippers transport live animals safely. They cover domestic pets as well as birds, reptiles, livestock and other species.

Even if a pet owner never reads the complete manual, LAR can affect:

• Whether a travel crate is accepted
• Crate size, construction, ventilation and security
• Animal welfare and safe handling procedures
• Marking, labelling and documentation
• Feeding, watering and ground-handling arrangements
• Route planning and airline acceptance

For the official scope of the regulations and the latest published updates, visit the IATA Live Animals Regulations page.

Key IATA LAR changes for 2026

The 52nd edition includes amendments across training, state and airline variations, species listings, documentation and container requirements. Changes most relevant to pet and live-animal travel include:

• Enhanced and more standardised live-animal training requirements
• Updates to state variations, including Great Britain
• Changes to the individual requirements published by many airlines
• Updated terminology for booking and advance arrangements
• Revisions to species names and classifications
• Updated container illustrations and construction terminology
• Clarification of ventilation and absorbent bedding requirements under Container Requirement 1

IATA also publishes addenda during the year. This is one reason compliance should be checked against the current airline and route requirements rather than relying on an old checklist.

Why pet journeys are delayed

1. Non-compliant travel crates

A crate may be refused when it is too small, poorly ventilated, insecure or unsuitable for the animal. Common problems include:

• The animal cannot stand naturally, turn around and lie down comfortably
• The door or fastenings are not strong enough
• Ventilation openings are inadequate or obstructed
• Water containers are missing, inaccessible or poorly fitted
• The crate materials or construction do not meet airline expectations
• Wheels have not been removed or securely disabled

JCS can help source and check a suitable crate before travel. See our made-to-measure IATA crates.

2. Incorrect or incomplete documentation

Pet travel paperwork is route-specific and often time-sensitive. Delays can occur when:

• A health certificate is issued too early or too late
• Microchip and vaccination dates do not align
• An import permit has not been secured before booking
• An original document is required but only a copy is available
• The airline, customs team or destination authority requires additional evidence

3. Airline and seasonal restrictions

Airlines may restrict animal travel during periods of extreme heat or cold, limit certain routes or aircraft, or apply additional rules to particular species and breeds. Acceptance can change, so route feasibility should be checked before travel dates are finalised.
