Thanks, EGGC, for the update. I seem to recall that there used to be some PIA flights to Canada refuelling at Manchester as well up to a few years ago - they must fly non-stop now from Pakistan if those flights are still around?
Otherwise, two 777-200 and two 777-300 flights from Karachi to JFK. What do you think - will those flights continue to be safe or could PIA be persuaded to send a 777-200 to Dublin first and clear US Immigration?
I'd still prefer the Air Blue A321 coming to Cork from Pakistan and doing that refuelling in Turkey!
