YEG, gate agent refused to allow my carry on which was 500g exactly over. Said i wanted to carry on instead of checkin , made me open it up so i had to make it 1kg lighter. in the meantime, caused me to miss my flight from YEG-YYC and wait again in the queue. No star gold or biz agents around to checkin for the flight. Declined to issue me my connecting boarding pass YYC-FRA. All in all, typical poor service and poor product from AC. Additionally earlier when in YYC on the way to YEG, wanted to speak to an agent about ticketing, there was a queue of 15 people with one agent in ticketing, with about a dozen people in checkin, sitting there doing nothing, went up to ask a very simple ticketing question and was told to go back and wait in the ticketing queue where this single rep was working. Waited there for 1 hour and gave up...... there must be easier ways to earn miles for flying in Canada.... than flying AC.
