PIT does have a very fine facility...but a sad aspect of the post 9-11 world is the prolonged affects and toll it has taken on our airports.
The terminal use to serve as a source of shopping and dining for the non-traveling public too. The new security measures have now killed that. The Air Mall in PIT is seeing a number of stores scaling back or closing due to decreased revenues.
The latest retail victim in PIT was "The Discovery Channel" store. Thier last day of operation was 24 Dec. 02. This for me was saddening...I always enjoyed shopping there. Many times I made specific trips from CLT to shop there...now I'm in PIT and it's gone.
