Have you checked routings to YHZ or elsewhere in the Maritimes, via YUL? Or even YQB via YUL. You'll likely have to book through AC res, and spend a Saturday night at the other end. It is in getting cheap, multi-segment routings that western Canadians, and particularly those in Alberta and BC have much more opportunity that us back here in Central Canada. One more example of how beneficial it is still having AC service out there.
