Missing 1st leg of multicity trip
If I have the following itinerary:
Kingston to YYZ 28 Oct 2017
YYZ to NYC 13 Dec 2017
NYC to Kington (through YYZ) 5 Jan 2018
What happens if i miss the first trip, either by just not showing up or by calling air canada and notifying them that I can't make it? Will the rest of my itinerary still hold, or will they cancel everything?
