If you're thinking about traveling by air with a pet sometime soon, this video can help simplify the process for you. The video mentions using a "USDA-approved" travel crate however there is no such thing. The United States Department of Agriculture doesn't oversee travel crates. The USDA is in charge of monitoring the import and export paperwork and ensuring the health requirements are fulfilled.

Instead, crates must be compatible with IATA's Live Animal Regulations.The regulation depends on the type of species you are flying.

Nevertheless, this is a nice video for someone who wants a quick overview of air travel for pets.
