Airline transportation for pets can be tricky. As many equestrians and others working within the industry know, travel is simply a part of the job description. Whether you are traveling from the office or for competition, there will almost always be some form of airline experience involved.

As animal lovers, many equestrians would never leave their trusted dogs (or cats) behind. But which airlines are the safest for our beloved pets? Which are the most pet-friendly? And which have a track record of being the most dangerous? Not every airline is the same when it comes to compliance and safety for our loyal companions.

Ready for Take Off

Whether you are traveling with your canine or feline friend, it is important to do your research prior to departure. These days, there are many more airlines that accept pets on flights, but not all airlines have the same pet policies and procedures.

For starters, it is important to contact the airline you are traveling with directly for the most updated procedures, travel guidelines, and requirements. Some policies require mandatory use of an airline pet carrier, or charge a pet fee. Knowing this information can be the difference between a smooth flight or a nightmare.

The following statistics on the best and worst airlines for pets were compiled using reports from the United States Department of Transportation.

The DOT requires that a monthly report is submitted from each airline indicating the deaths, losses, and injuries of an animal during air transportation; it is public information that can be found archived through the DOT Consumer Report.

The number of companions traveling since 2015 has been steadily decreasing. Beginning in 2015, a reported half a million animals flew with U.S. Airlines. By the end of 2019, that number had decreased by 25% with only 404,556 animals flying during that year.

To further this decline, the COVID-19 pandemic generated another 25% drop in 2020, with only 311,149 animals boarding flights.
