The following information has been collected from the airlines’ published pet policies. It was last updated on April 16, 2013.
For each airline, I have provided a link to the airline’s pet policy. It is a good idea to print out a copy of your airline’s policy, so that if a dispute arises with an airline agent, you will have the actual policy to refer to (not the agent’s potentially faulty memory of the policy).
Please note that the kennel sizes (e.g., Series 500) refer to PetMate Sky Kennel sizes, which seem to be the industry standard. Other crates besides PetMate crates will work, as long as they conform to the IATA Container Requirement for cargo-area airplane crates.
