Stepping into the Interfaith Reflection Room at the Pittsburgh International Airport is like leaving the busy airport behind entirely. The large and quiet space is located on the mezzanine level of the airside terminal, next to some bathrooms and a private lounge. On the inside of the room are a few dozen plastic chairs facing two pulpits and a removable wooden crucifix on the front wall. The room is clean and bright. One wall is painted red with a long window at the top and a few multicolored stained glass squares in the corner that let in lots of light.
