I had the earliest one off all with FFL-YYZ arriving at 1:24am on Jan1. Cancelled 5pm on the 31st due to "crew" issues. I imagine it was because it was empty (though full coming down to FFL). So annoying.

How do I get AC to pay for the extra day I needed for my rental car?

AC does not cancel flights because they are �empty�. That would put the aircraft and crew in the wrong position and cause all sorts of downline issues and affect numerous other flights.

Interesting.

What a gong show at YYZ this evening. Congratulations to anyone that managed to find a seat in the MLL or cafe, bonus points if your flight left on time!

Just a bit of snow. but eh, that's YYZ. :-)


Apparently an Emirates 380 waited three hours until they got a gate. Good for them. :-). At that point snow was a mere 24 cm apparently.

No shortage of AC signature rolling delays and unscheduled maintenance cancellations either� not a fun time to be non-elite pax (or even anyone who doesn�t know (how) to proactively rebook/not wait on hold/put yourself on standby etc)

AC1002 delayed 4 hours to 13:30 today. Yesterday it returned to YUL after making it as far as the Catskills. AC1007 was also cancelled yesterday.

Trying to find the correct fin operating AC1002 this morning, there was conflicting info between FR24, Flightaware and the AC website of what fin would operate the flight. Looks like lots of FIN swaps and cancellations over the last few days.

I'm guessing some weather (probably more spillover from the excrement-spectacle known as YYZ with weather than actual weather at YUL..side note as a Canadian, I'm embarrassed how YYZ handles even the smallest amount of winter weather) but it does seem that the A330s dispatch reliability is taking a hit these days.

I find FlightStats has the most information on FIN swaps, because it gives you the whole history.

But I'd assume AC is going to be the most accurate.

Embarrassed? Smallest amount of winter weather? We got over 30 cm in a lot of places around YYZ, so it was a substantial dump of snow which required de-icing of every flight and surely slowed ramp activities as well. We all know that the schedule is tight in optimal conditions so it should be no surprise to anyone when a major weather event hits the country's biggest airport that there will be delays that will have knock-on effects in other places which sometimes take days to fully recover.

I was not referring specifically to this storm was on the larger side, but more of a general observation that even 5 or 10 cm of snow brings YYZ down to a crawl. And that usually totally screws up YUL as a consequence.

Winter schedule block times are usually adjusted for deicing.

Also, this is not just my opinion: This is just one. From the Journal or Airport Management in an article: "Montr�al-Pierre Elliott Trudeau (Montr�al-Trudeau), Canada's third-busiest airport, receives 220cm of snow a year on average, which is more than any other major airport in North America. Yet, in over 70 years of operation, the airport has never had to suspend operations for more than a few hours because of snow. This is made possible by employing state-of-the-art equipment and the application of a number of best practices that have made Montr�al-Trudeau's winter operations a model for snowbound airports around the world."

When booking any flights I actively try and avoid YYZ, most especially November through March.

AC1864/1865 YYZ-CUR and the return 1865 delayed "only" 5h30m today, meaning I'd get in to Pearson at 3am (and have to wait several more hours for rental counters to reopen).

With 10h30 round trip flight time, plus 1hr (?) preflight report time and 40m min turn), a new crew was needed after ontime boarding & short maintenance issue. That's when several extra hours were added.

the app shows an equipment swap although the actual vs scheduled fin # was unchanged

This doesn't affect me as I ended up returning from YYZ earlier than expected, which I am grateful for, but this is the flight I would normally take out of Toronto so I am curious about the cancellations this week. AC 1119 is cancelled yesterday, today, and tomorrow. EF has "Weath" in the notes, which I take to mean "weather". I know it is horribly cold in Regina (-36 overnight) and the weather isn't great in Toronto overnight but it seems odd to me that this flight in particular isn't operating. The YVR flight tonight is still on, and everyone else is coming in as well, so if a Dash-8, a couple of 738s, and a CRJ-900 can overnight at -36, then why not an A321 and an A320 (tomorrow)? It was only -28 last night, so not even that bad.

Having asked that question, I had a look at YWG and YXE arrivals and see that AC271 and AC1937 were cancelled yesterday and are also not operating tonight or tomorrow. I guess I don't recall noting so many cold weather cancelations since the early days of the E190s when it took a bit of time for AC to figure out how to keep the water lines from freezing overnight, but definitely there seems to be an Airbus pattern across these three airlines. I am not aware of cold weather affecting AC's Airbus aircraft more than other types, so I am definitely curious.

Simple: Airbus aircraft are inferior copies of existing better designed models, but we already knew that.

On a more serious note, I am aware of A320neos with PW engines having special procedures for taking off in cold weather, but that obviously does not apply.

This may not be directly related to weather at these airports and part of a larger strategy for mitigating the overall network operations given what is planned for the weekend. AIrlines are getting better and better at proactivly cancelling flights to be fully operational sooner after a storm These may be richochet effects of other cancellations down the line.

AC is proactively making a number of cancellations this weekend due to the weather forecast in YYZ in order to keep the operation stable and give customers advance notice/options.
YYZ cannot handle the same number of movements in extreme cold for a variety of reasons. Heavy snow forecast for Sunday is the icing on the cake.

Looking at the YYZ forecast, I don't see anything that resembles extreme cold.
