Round and round we go as there is simply nothing concrete to talk about long haul wise from BHX right now (or even in the near future despite the runway extension) so nostalgia and wishful thinking is all that's left......ONLY for sake of completeness, I am amazed that no one has mentioned that BA also used to fly BHX-YYZ (admittedly via JFK) on a 757 for at least a year if memory serves me right......along with Nationair and Canada 3000 at some point and Globespan to Toronto Hamilton.
The vast majority of AI and PK pax on BHX-YYZ were in transit, they used to pick up a handful of pax at BHX, normally single figure loads. PK in particular were only ever allocated one or maybe two check in desks for transit flights as there were so few BHX originating pax to check in.
