BWI Viewing Area
 

Is the BWI viewing area groundside or airside? I'm trying to find a convenient place to meet a friend (who isn't flying), and it seems not to be indicated on the map of BWI.

It is between Pier B and Pier C. It is outside of security. On the map its behind the F9 and DL/TZ ticket counters. I guess its represented by that grey/silver thing.

It's up a flight of stairs back there, and overlooks the tarmac between B and C. You'll see a lot of CO and WN metal. There are about a hundred seats, a small bar, and an interesting collection of old aircraft parts for inspection: landing-gear tires, a fuselage cross-section, etc.
