In a few weeks some family members and I will be taking a Jazz Dash-8 flight from YEG to YYC, and it is the only AC-operated flight on our itinerary. Am I correct to assume that (1) our rollaboards will be valet-checked just prior to boarding, and (2) that we therefore don't have to worry too, too much about possible excess inch here or there? Or (3) should I instead be warning family members that this is likely to be strictly policed at YEG?
