Last chance to see in October for PIA711 & 721 westbound EGCC Manchester to KJFK New York, usually with B77L AP-BGY or -BGZ. Often routes NW over Larne and the north coast.
The eastbound reciprocals are non-stop to Karachi and Lahore and usually route much farther north or south.
Pakistan International are ceasing all US-bound services as of 31 October and switching to code-shares. They will continue services to Toronto but those routes seldom approach NI.
