I flew on a day when flights across Canada were canceled or delayed. My specific flight was delayed 12 hours. I was also forced to take an additional flight, for a total of 4, to get home. These took me from Vancouver to Toronto to Montreal to Boston. I can only assume there was no option of getting me on a flight that cut one of these out. That said, I want to emphasize that I appreciate the efforts the staff and maintenance crew took to get everyone home safely. Maintenance found a leak in a water hose on our initial plane. I would much rather be delayed than fly on a plane that is in anyway unsafe.
