Airline Dog Crate Requirements: Cabin vs Cargo Rules

What are the requirements for a dog crate on a plane?

Airline-approved dog crates must meet a mix of safety, size, and construction rules designed to keep pets secure during transport. Exact requirements vary by airline and whether your dog is traveling in the cabin or in the cargo hold, so it’s smart to confirm details before booking.

General airline crate requirements

Most airlines require a rigid, enclosed crate that’s clean, escape-resistant, and in good repair (no cracks, broken latches, or sharp edges). Ventilation is a big one: crates usually need airflow on multiple sides so your dog can breathe comfortably throughout the trip.

Size and fit standards

Your dog must be able to stand up without touching the top, turn around, and lie down naturally. If the crate is too small, airlines may deny transport. If it’s too large, your dog may slide during handling, which can also be a problem for cargo travel.

Door, locks, and security

A sturdy door with a secure locking mechanism is required, and many airlines want the crate to prevent accidental opening during loading. Zip-tied doors are sometimes requested for cargo, but policies differ—check your carrier’s instructions before arriving at the airport.

Interior, labeling, and water provisions

For cargo shipments, airlines often expect absorbent bedding or a leak-resistant floor (no messy materials) and may require “Live Animal” labeling plus contact details. Some carriers ask for food and water bowls attached to the inside of the door and accessible from the outside, along with a way to provide water without opening the crate.

Cabin vs. cargo rules

In-cabin pets usually must ride in a soft-sided carrier that fits under the seat and stays closed during the flight. Cargo travel typically requires a hard-sided kennel that meets airline and, for many routes, IATA-style guidance.

FAQ

Can my dog’s crate have a blanket or towel inside for a flight?

Usually yes, as long as it doesn’t block ventilation and won’t bunch up in a way that could create a hazard. For cargo travel, many airlines prefer thin, absorbent materials rather than thick bedding that can trap heat.
