Yes, Air Canada has started messing with this after the first weekend of May. In Economy, they report the correct booking class, unless it is better than T. Then, only T is reported. That is my experience.

They did have "branded fares" before, so I dunno what happened. Air Canada customer service agrees that I should get more miles for certain flights, but in the end the other airline (program operator) and Air Canada can't seem to fix it.

Passengers are given the short shrift. We have similar reports from several other *A programs.
