United Airlines has a solution to your holiday travel woes.

The airline’s United Paws program is bringing hundreds of trained comfort dogs to airports across the nation to help ease stress before flights and welcome passengers to their destinations.

The program, announced by the airline on Twitter on December 18, kicked off yesterday and lasts through December 23.

“United Paws is a wonderful program that comes at just the right time for some holiday travelers who may be experiencing a bit of anxiety or stress,” Veterinary Consultant Walter Woolf said in a news release.

According to the airline, just being around a dog can boost your holiday spirit – but it can also help improve your health.

Research shows that petting a dog “decreases the levels of stress, helps us breathe easier and lowers our blood pressure,” Woolf says.

Many travelers are sharing photos of themselves with the comfort dogs on Twitter and Instagram with #UnitedPaws. United Airlines says that for each photo shared, it will donate $1 to the continuation of the United Paws program.

The pups can be found at seven lucky airports in O’Hare International Airport, Illinois, Cleveland Hopkins International Airport, Ohio, Denver International Airport, Colorado, George Bush Intercontinental Airport, Texas, Los Angeles International Airport, California, Newark Liberty International Airport, New Jersey and Washington Dulles International Airport, Virginia.
