What is an airline-approved travel crate?

IATA guidelines, widely used as the reference standard by airlines worldwide, specify ventilation openings on at least three sides, solid non-wire construction for most of the crate body, a leak-proof but absorbent-lined floor, and door fastenings that are secure but do not require a padlock, since staff may need quick access in an emergency. The crate must also be large enough for the dog to stand at full height, turn around fully, and lie down in a natural position.

A sturdy plastic crate sold generally as durable or heavy duty does not automatically meet airline specifications, since features like wire mesh sides throughout, rather than mostly solid walls with ventilation strips, can fail cargo requirements even though the crate is perfectly fine for home or car use. Checking a product listing specifically for IATA compliance, rather than assuming general durability equals airline approval, avoids arriving at the airport with an unsuitable crate.

Beyond the base IATA standard, individual airlines sometimes add their own requirements, such as specific labeling, a leak-proof tray secured a certain way, food and water containers attached to the inside of the door, or a particular type of door latch. Confirming directly with the airline before purchasing or finalizing a crate for a specific flight avoids a mismatch between a generally compliant crate and one airline's particular rules.

Labeling the crate clearly with the dog's name, your contact information, and destination details, along with attaching a recent photo, helps in the rare event of separation during handling. Freezing a water bowl attached to the inside of the door so it melts gradually during the flight is a commonly recommended trick that provides water without spilling during loading.
