A and B are connected. A was very nice, it looks like it's b's turn to get some work. When you go thru security, there is a part of B that they have covered up. The sign lists a bunch of new eating places that there planning on adding. I ended up flying in and out of both A and B. It seems like they could of added some more seats in the waiting areas. It did get a bit crowded.
At the end of A, there was a sign saying about ongoing filming of Airline at at that end. I didn't see any familiar faces, or cameras. I did take a pix of the sign though!
