I hear all those points but it does seem like you are trying to find every way to say there shouldn't be flights from the US to NOC. Surely if NOC can attract an airline and make it work, whats the issue? Whilst I agree NOC is not exactly the epicenter of global aviation its done very well in the last few years and whilst the arguments for being business friendly and having links to say LHR do carry some weight, I think if it was likely to happen it would have done by now. Given that the airport has 3 daily flights to LON, daily to BHX, up to daily MAN,LPL,EDI,BRS and various scheduled and charter sun routes even Turkey this year why on earth not the US? Its much more likely to win on a US run than trying to flog a dead horse on european routes or yet another LON flight.
I smell a twinge of fear in some of the posts on here, that NOC may take from DUB or SNN, otherwise why the fuss? If you think it will fail don't worry, thats a mistake NOC would have to live with.
