I think you'll find the difference between Lufthansa and Germanwings is that Germanwings are an already established STN resident, so comparing them to the efforts of LH back in the day @ STN is somewhat unfair. However I have no doubt that they are trying (and will succeed) in seeing Darwin/Etihad off the route. It's just a shame we've said goodbye to AB.
I'm assuming the LH flight number allows for connections @ DUS?
