With some of the upcoming fleet changes, there are quite a few schedule adjustments happening, and a few routes being upgaged, but with frequency reductions.

For example is YOW-YEG which currently has 2 Westbound E90 flights is moving to a single evening A320 flight. On YUL-YYC, you currently have up to 5x/day:1 A320, 2A319 and 2E90. The winter schedules moves to 3X/day on 2A320 and 1E90. True, some of it is pure seasonal adjustments - but some of it is also impacted by the larger planes now being used on those routes.

One nice adjustment I have seen to the winter schedule though is that Ac145 (YYZ-YYC) is now departing one hour earlier (as another flight is being removed) and upgaged to 763 service (from a 321). What this means is that the redeye from Calgary back to YYZ now has the pods!
