I travel often so I've been through several airports. Pittsburgh is one of the easiest ones for me to get through. Maybe it's because I know it so well but I do think it's a more pleasant experience than others. All of the employees I have encountered here have been pleasant. The restrooms are always clean no matter what part of the airport I am in. I also noticed a sign that they now have a nursing lounge for mothers. So cool! I love when an establishment thinks of the needs of different people. When the security lines are extremely long we are still able to get through them in a decent amount of time. They also have an additional security area to help with that issue. There's a nice variety of places for any needs such as ibprofin, food, water, magazines and so on. The assortment of various food spots is nice. I always love seeing the dinosaur in there welcoming you back. Safe travels! Hope your experiences here are equally as good.
