French Bulldogs, Pugs, Boston Terriers, Persian cats — brachycephalic (snub-nosed) breeds are among the most popular pets, but they face the most airline restrictions. Their shortened airways make them vulnerable to respiratory distress during flight, especially in cargo holds. Here's what you need to know.
Snub-nosed breeds have compressed airways that make breathing harder, especially in stressful or temperature-variable environments like aircraft. Historically, brachycephalic breeds have had significantly higher incident rates during air travel. This led most major airlines to implement restrictions.
The risk is highest in cargo, where temperature and pressure fluctuations are more extreme. Cabin travel is generally safer because the environment is climate-controlled and you can monitor your pet.
