No way today's result should count towards the final standings, with so many top athletes not being able to compete simply due to airlines messing things up. Seems like Nika Prevc got lucky and had her things right on time, but all the Canadians were simply screwed.
Best solution would be for the competition to be held as normal, of course, but not counting towards the final standings. That way, it's still a perfectly valid World Cup win, podium and so on for those who get those results, but those whose stuff is missing aren't punished.
