$400 will get you Priority Pass lounge access.
If the OP is doing 80ish segments between YVR/YEG/YXS, I suspect many of those are without luggage. If you don't have luggage, there isn't much need for priority checkin.
When flying YVR-YEG-YVR, check the price of T+ to LAX. The difference may be less than the $67 AC currently wants.
