I received a flight cancellation notice on one of my legs today at 1400 when the flight was scheduled for takeoff at 2130. The issue was apparently freezing rain at the departure airport. Other interesting fact is that other flights form the same airline were scheduled and took off to go to another destination and come back in the same timeframe we were supposed to takeoff.
The reason given by customer service: weather. The customer service rep also slipped that Jazz had issues filling their lines because of manning today but then insisted it was for weather. Is it a deliberate attempt at deception to avoid having to honor their tarriff?
Weather can have an issue down the line that you might not see. If for example, YVR was fogged in first thing in the morning and the airplane was unable to leave, it would cause a ripple affect for the rest of the day. That plane might have been scheduled for 5 legs today and maybe the last YYZ-YYC, might have to be cancelled as it would be too late, or they might run out of crew duty etc.
There are a number of factors that would got into deciding to cancel.
Was the crew for your specific flight there for the intended departure time or in time for a reasonable delay? How about the equipment itself?
The reason I ask is because the Operations team for your chosen airline may have foreseen that either was not available to accomplish the flight and it's possible that cancelling yours may have had the greatest reduction in downline impact to the overall business.
Regarding the reasoning behind the cancelation of the flight in their system, at the front line, you may only see that the aircraft was not there, or the crew is not available to operate your flight, which is why it might lead you to question their justification and tariff rules, however the root cause for the inability to service that one flight could have been upline weather.
IROPS are certainly a pain.
YUL-YVO (you said that flight went) is not quite in the same direction as YUL-YBG. There could be different weather affecting east/west from Montreal.
The crew /equipment could be affected down the line, in which operations (together with AC) determined well in advance, the would not have the resources for the flight. A good example is the crew currently in YBG is stuck there due to weather. They don't want to send more planes/crews there, because then they would have MORE of a problem.
Again, without my knowledge of the weather today, sometimes operations has to prioritize flights with what they are given because of weather. What they are given, meaning, slots, equipment, crew. Sometimes they will have to purge these flights ahead of time, to inact a plan to start recouping their cancellations, sometimes combining flights on bigger aircraft, or half empty flights to full flights etc.
Good luck getting to YBG!
The argument was made by the regulator that the cancellations were predictable and that the airlines should have been proactive with flight cancellations and given passenger notice.
That is the reason for advance flight cancellations. It is now considered an obligation under the licence issued by the CTA.
The conspiracy theorist
The airport authority, or Nav Canada? I believe the way it works is that weather is, or is forecasted to, affect(ing) an airport. A conference call is held including all all affected parties. Nav Canada reduces system capacity, and the airlines are forced to share the leftover capacity. I’m not 100% on the specifics of it, but I don’t think, in Canada, the airport authorities reduce traffic due to weather. That said, they could close a runway for snow removal, which forces Nav Canada’s hand.Quite often it is the airport authority that says "hey bad weather cometh, we cannot deal with the capacity, you must reduce your schedule." So basically, the airline has to "streamline" the schedule in advance of a known weather event because the airport cannot handle it. Your airport improvement fee dollars hard at work.
