hello again,

can't speak for NA flights, however, in the 90s, the flights i took from LGW outbound flights mostly on cx220 (direct)/200(via BAH)/260(via CDG))/290(via ZRH) all arrived in hk between 0700 to 0800. And i definitely saw the board showing that there were flights arrived before my flights did. I would imagine most likely they would have flights arrived before 0700 even in the days of kai tak.

cheers
