Hi,

I am looking at a flight from a US city to Calgary to London with Westjet and wondering about lounge options in YYC.

SFO-YYC (international) - it looks like I'd arrive in concourse D?
YYC-LGW (international) - I understand this departs from concourse D?

My understanding is that the elevation lounge is in concourse B. The Westjet website notes that "Guests departing from Concourse D in the International terminal can access the lounge via security checkpoint B or C before proceeding to Concourse D". How does this work for connecting passengers?

Do I need to transfer from concourse D to B as if I were making a domestic connection (pass through immigration, etc.) and then trek back from B to D?
