Okay so my YUL-ZRH flight got moved forward 10 minutes and leaves just 40 (instead of 50) minutes for my onward connection to VIE. I understand this is MCT and had I been on my own would not be so worried however rather concerned given it’s myself, my parents and little brother (10) so if we were to miss a flight/be delayed in YUL for snow (my booking is right around Christmas), finding 4 J seats on another might make rebooking difficult...
Complete itinerary is YUL-ZRH-VIE-IST.
