We tried out CP thinking that it was going to be a better airline to fly. Our parents used to fly CP transpacific. The flight was late boarding and departing. Notifying passengers with connecting flights is important but we didn't hear much from the ground crew. The flight crew were quite friendly and accommodating. Lets just say there's not much to write home about.
