Are you afraid of taking Rover with you on your next flight because he might have to go potty in the airport? Well, pet-packing passengers flying through San Diego’s Lindbergh Field can rest easy. The airport’s recent $1 billion “Green Build” Terminal 2 expansion includes the nation’s first and only “pet relief” comfort station. Located between gates 46 and 47, the 75-square-foot rest room is decked out with features to get your four-legged friend in the mood to go, including ersatz grass and a fire hydrant. This may be the first, but it won’t be the last. Tom Rossbach, director of aviation architecture at HNTB, told the San Diego Union-Tribune that the firm is offering the amenity to its other airport clients.
