...what is the minimum recommended connection time on an international itinerary through YYZ in mid April? Specifically, AA flight arrives into YYZ @ 11:55pm from ORD, and we are connecting through to Cathay's YYZ-HKG longhaul @ 1:40am...Flying in biz on AA, F on Cathay. Is 90min enough time to clear immigration on a Friday night/Saturday morning in YYZ and then re-check in for the TPAC, wondering if Cathay even flies out of the same terminal as AA?
