I spent Sat night at the YVR Fairmont and had an airside view again. Couldn't help but notice that on HQ 757 sat on the tarmac for my entire stay whilst another 2 came and went from Transborder over the course of 24 hrs. I always thought that airlines only made $$$ when the planes were actually in the air.
There is always one spare HQ aircraft parked in YVR and once a week there are two.
