I suspect it will. I saw a comment in one of the presentations given on I think it was the first day, and the commentary was that it shouldn't if the air carriers “up their game”.
I find that somewhat puzzling. I can't up my game if I'm taking delays because we have guests stuck in CATSA. I can't up my game if we have delays in conveying information with regulatory authorities in the other country for aviation security purposes and I'm not getting information back as to whether I can go or it's no-go with that passenger or passengers, and therefore, I'm delaying the flight. I can't up my game if there are delays at de-icing facilities that I do not control and that I do not operate. There's no way around that.
