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.
