This change is absolutely ridiculous. Incredibly frustrating for those of us who book are tickets via OTA or powertools. Also not sure if its related but looking at some sample dates from YYZ-YHZ over the next few months, I can't get flex for cheaper than $375 and its showing mostly around $415. I used to be able to book flex ~$320, even high 200s sometimes.

Edit: Played around with Matrix for a bit for YYZ-YHZ. Can't even get it to pull up any G or W flex fares at all. Only displays tango. In order to get flex you need to search V fares on matrix, while AC.com can at least pull up FLEX G. This is incredibly annoying.
