Also, EK operate the 77W non-stop from DXB to JFK, can PIA not do the same with theirs or is the few '000 mile difference too big a difference?
Is this not something to do with the US authorities not allowing non-stop flights into the USA from Pakistan because of security concerns? This was certainly the case a few years ago. All transit pax on the PK US flights through MAN must clear security at MAN so the Yanks know they are cleared to UK standards which they accept.
