NUE must be the most important city / region in Germany not to be connected to either MAN or BHX.
How about the lack of BHX to BER direct? No more from baby on this....
As for getting Brits to visit Frankenland, thats going to be even more difficult. On the whole we British just don't "do" Germany (except for Christkindl and the Bierfest).
I think the likes of EZ are bringing plenty of people in through SXF, and Germany is surprisingly high on the list of top tourist countries. CGN also has numerous links, and HLX are opening up more routes to/from EDI, NCL etc this year.
When in Berlin last October, I had several people responding with "wadduyamean mate" when I asked them "sprechen Sie Englisch"! BTW, Google's language tool has English > German as top of its list, not Spanish or French.
