Hi, planning a trip to China and finalizing airlines. Air Canada is offering great connections at a good price, so I am thinking of trying them. Am looking at LGA-YYZ-PEK going out and PVG-YYZ-LGA coming back.
How much time should I allocate for transiting? The standard 1.5 hrs that I follow for Europe or should it be longer? Its been a couple of years since I flew to Canada but I recall we had to clear customs and immigration in Toronto - I assume I would have to do that on my return flight? Is there anything I have to do on the outgoing flight? I'll be in business class, will that help with the lines?
