Skipness it was a Tristar and it routed via Munich when BA flew Manchester to Hong Kong.
Not since 88 it wasn't. I only say that as that is when my personal involvement at MAN started.
MAN-LHR-HKG was a 747. Terminated at MAN and routed through LHR (or was it LGW I forget)
The Tristar was used on the MAN-JFK. That swapped around a bit due to the 'merger' with BCal and changed several times from a 747 to a DC10 before the 767 arrived.
We had it on good authority from a senior BA manager a couple of years ago that there would be no return to regional longhaul ops until the 787 arrived.
Don't hold your breath.
