Nuremburg is an awfully long way in an ATR72 from London
I flew on a Eurowings ATR from STN to NUE back in 2001. If recall correctly it was flown on LH flight numbers. Didn't seem to be that arduous. Subsequently I used the excellent Air Berlin service until it was shifted to LGW which was inconvenient for anyone travelling from north of London (or in my case, the Midlands).
However, NUE is primarily a business route, with point to point traffic, but it never seems to work at the frequency that business would like - that is 2 x daily.
I would say it is a prime route for FlyBe - but not from SEN. BHX
might make more sense - but I wouldn't put my house on it.
