Thank you for your replies. I still remain a little befuddled as I flew into A17 tonight from PHX for business. After I walked back out security, I saw signs saying to the skytrain, Terminals B,C,D with arrows pointing down at the elevators. I took the escalator down to get the rental car shuttle, but all such connecting to other gate signs vanished.

How does one get to B67 from the A terminal without leaving security? You'd think by my dumb a$$ question I travel once annually so I apologize. I guess I could take the rental car shuttle over since after it leaves the A terminal it stops at B, hop off, and get on the sky train.

PS. Thanks for the smoking info. I only asked in reference to the lounge smoking as even at DFW which is a smoke free airport, the Admirals Club has a smoking lounge in it, so I was curious as to the British Airways Terrace lounge where I will have access to use with my CW ticket.
