Every year, the PIT PAWS (Pups Alleviating Worry and Stress) therapy dog team embraces the spirit of Halloween to the delight of travelers and airport staff alike by wearing fun costumes throughout the terminals.

The team’s goal is to bring smiles and comfort to people who may find air travel a bit stressful, and dressing up as superheroes and more fits right in with their mission. Enjoy this gallery of our favorite furry friends trick-or-treating at PIT.
