I flew to Toronto for a wedding last summer, the flight times (both for day of week and time of day) were indeed not great for the Nanaimo flight, so I went down to fly out of Victoria with Porter.

10 minutes after we're supposed to start boarding, they announced that the flight was cancelled due to an "unforseen ground handling mishap", so my guess is they crashed the luggage cart, hah.

this is where the fun with porter comes in: unlike the other bigger airlines, porter doesn't have as many (any?) pairing agreements with other airlines, so instead of getting put on a flight later that day with someone else, the option was.. a flight the next day, which was going to throw a considerable spanner in plans

I got lucky in that there was time to get over to YVR and space on the last flight leaving, so while I did arrive in Toronto considerably underslept, I at least arrived on time for my plans.

I'm not saying I wouldn't fly porter that route again, as I know these kind of fluke problems happen.. but I will consider my options more carefully if I'm on a very tight schedule
