Pittsburgh international is a smaller airport I would say. Maybe small is not the right word. Quiet maybe. Pittsburgh used to be a hub but after the fall of us air they have declined a bit. They try. Southwest has become a major carrier in and out (I don't mind they tend to be pretty cheap with lots of options that don't require layovers). It is usually easy in and out. Sometimes parking there can be tough. Parking far away...but overall it is okay and it is close to home so that is a nice thing.
