I am flying F on June 10 to HKG, trying to decide on YYZ or JFK. I have to come in the night before from Miami as both are morning flights and too early for a connection. My thought is JFK may be easier as I can check the luggage all the way through to HKG where as in YYZ I have to clear customs and retrieve my luggage. Any feedback to which way you would lean? Both seem to be on the 773 plane so I think its the same in that respect. On the return it an easier decision as the YYZ flight gets in early enough for a conection back to MIA same day where JFK does not. I know LAX is an option but I am not wild about the 5+ hour transcon on AA first product.
