The Best Travel Dog Carriers
By Chloe Dubois0
The Sleepypod Air is the crash-tested cabin carrier for pets 18 lb or less. It compresses under the seat, then expands once you are through takeoff.
Travel carriers differ on under-seat flex, crash testing, and how you load the dog. This guide compares five named soft-sided models built for cabin flights and car rides.

- Material: Soft-sided expandable shell with four ventilation windows, privacy panel, luggage sleeve, and padded shoulder strap
