Does indeed sound very promising.
Cornwall-Germany is a huge market. Tbh I'm surprised that LH group or flybe haven't jumped onto other German routes and I'm surprised that the DUS is still 1 weekly, DUS has previously been 2 weekly with a CRJ plus a mainline 735 if my memory hasn't completely failed me !
I would expect 2017 will see either LH group adding German destinations or if flybe add to the NQY based E95 to see flybe on German routes ex NQY.
I understand that th current flybe NQY based E95 is doing good numbers to both LGW and MAN so this is also very encouraging. I suspect of numbers continue to rise that we will see MAN go double daily for summer17 with morning and evening rotations to open up the full range of connections available at MAN BE-BE/VS/EK etc
