I've not commented for a while, firstly OltonPete, many thanks for your analysis of trafic and comments.
Regarding the link from HS2, if they replecate the link in Paris from Antony to Orly then thay cann't go too far wrong. Its a great high speed low capacity link.
A general observation is that BHX is finally receiving proper service (i.e. 737/A320/MD80) planes on the trunk EU capital routes. The traffic on these routes has increased accordingly and long may it continue.
I am concerned with the United EWR link especially as my family are booked on it via EWR to Floriday next easter. We have travelled long haul a few times in recent years and it is always much more expensive to the USA from BHX than LHR, even against a 757 from LHR. As least Emirates seem to keep the same prices between MAN/BHX/LHR. United must make a load on this route based on the prices?
