There was a recent thread about KLM swapping the planned aircraft type for a particular flight at the last minute. Given the large and varied fleet of long range aircraft in the KLM fleet, it seems they do have many options when it comes to aircraft choice for specific routes. I've noticed here at CYYZ (Toronto), KLM's aircraft choice does tend to vary significantly from the "planned" types that are expected. After checking Flightaware historical data, it seems about a 20% chance of getting a different aircraft type than the one that was planned. At CYYZ, I've seen B777, B747, A330, and MD11. We have NOT yet seen a B767 but they have operated to other Canadian cities.
On the other thread, "AvroArrow" posted that "While the unpredictability of the aircraft type may be frustrating to some, you can't blame KL for trying to find the best match for the route on a given day."
My question for this thread is: Do most of you think that KLM makes these aircraft changes to line the capacity up with demand OR are most of these changes caused by mechanical issues / delays on the day of operation?
If they are indeed trying to find the "best match" , I commend their OPS/Dispatch people given the range of aircraft at their disposal and the complexities that this must involve on the day of the flight. (front + back end crews, catering, cargo capacities, different seating capacity and config etc...)
I worked for Air Canada Toronto Station OPS a while back and it was sometimes difficult to engineer an aircraft swap for the same type because of different galley configurations (B767-300s). Any thoughts would be appreciated.

I don't think that it has to do with pax demand. KLM probably swaps the aircraft due to logistic reasons.
For instance.... they usually have an extra 747 flight deck crew in NY for possible operational changes. These crewmembers can easily be sent (deadheading) to another city.
Most cabin members at KLM are 747 qualified, so you'll find that a swap on a Canada or US flight will probably be from an A330, 777 or MD11 to a 747. Not the other way around.
And ofcourse a downgrade from 77W to 772, or from 744 to 74E will likely happen when an aircraft becomes unavailable (operational issues).

I am under the impression that by far the largest number of aircraft swaps take place on North-East American cities,
such as JFK, YYZ, YUL, IAD, and that the rest of the network is significantly less affected by this phenomenon.
