Alaska Airlines is the first major U.S. airline to ban emotional support animals

Starting January 11, Alaska Airlines will be the first major US airline to ban emotional support animals.

The move comes after the Department of Transportation revised its air carrier access law on Dec. 2, which no longer classifies support animals as service animals.

“This regulatory change is good news as it will help us reduce disruption on board while continuing to accommodate our customers traveling with qualified service animals,” said Ray Prentice, director of customer defense at Alaska. Airline in a press release.

As part of the new policy, the airline said passengers should complete a DOT form which shows that “the animal is a legitimate service dog, is trained and vaccinated and will behave appropriately during travel.” .

Alaska said it will continue to accept emotional support animals as part of its current policy for flights booked before Jan.11 and flights on or before Feb.28.

The airline has said it will not accept emotional support animals on its flights after February 28, the company said.
