KLM reduces YYC-AMS service for the winter season

According to the Airlines Route Updates blog KLM will be reducing its Calgary to Amsterdam service to 4x weekly for the winter season. When KLM launched this route in May of this year it ran at 4x weekly for the first month and then increased to 5x weekly for the summer season. One can assume the numbers are good enough to keep the flight going but still not high enough to see the daily service that KLM envisioned when the route was first launched.
