When they had construction and had a mini lounge.

My last trip to YVR, the YYR domestic lounge was packed. Less than 5% seats were free and I had to ask someone to move their bag. Quite often I use the PP/Amex lounges because even though they may be smaller they are quicker to get in/out off and always space. I am based in YYZ and rarely use the MLL domestic or TB. The elevator wait and time to check-in is the issue though the lounge is not normally full.
