Rutankrd, please do not be so insulting towards me!
I did not even mention Liverpool in my post, nor did I contemplate avlink between Liverpool and Heathrow.
However, now that you mention it. Liverpool is a different city now than it was in the days when British Midland operated between Liverpool and Heathrow. And, the problem with BMA in those days is that the code-share phenomenon was in its infancy and the airline interlined with only a handful of airlines at Heathrow.
So, no sour grapes hear I am quite happy to use the train to get to London and Heathrow, or use Aer Lingus via Dublin when the need arises.
Incidentally, I would not agree that the Manchester Airport railway station is well positioned if you are using Terminal 3.
