Yes we knew CX was ending DUS as part of the 3 new routes CX is launching.
There were talks, but nothing was truly confirm (or, in better word, "make official") until now.
German-Singapore routes are stronger due to Star, but I am also not sure how SQ can sustain DUS that much when BER could not work.
DUS has a lot more business traffic in general compare to BER. Doesn't help that the new BER will probably open in 2046.
Bottom line, though, with AB more or less going into history book sooner or later, it reduced DUS to pretty much O&D, and such traffic can be served via the like of FRA/MUC.
BER has two things going for it as far as East Asian markets are concerned thou:
1. Tourism. BER is simply too famous a city to be entirely ignored for long-haul casual travelers. While FRA has long served as Germany's gateway due to the cold war and all that, it is just a matter of time where tourists would prefer to just go straight to BER, especially considering there is comparatively less tourist interest in FRA (sorry to my friends in FRA) itself and FRA involves backtracking from the eastern part of the world.
2. Gateway to Eastern Europe. As East Asian tourism and air traffic continues to grow, more travelers want to go to more "exotic" destinations, and Eastern Europe fits the bill (probably not that exotic to Europeans, but hey...we are talking about East Asians here!
). Much of Eastern Europe is still poorly linked to East Asia in terms of non-stop flights, and the ME3 + TK has been exploiting this. However, not all of us wants to transit via the ME, or to use any of those airlines. BER fits the bill very well here, both for it being a destination in itself, and for the convenience to either make a transit, or to use high speed rail to Eastern Europe.
I hope that with the airlines scaling back on DUS, that they may reconsider BER in the near future instead. Pity about the airport mess there however!
It's huaiwei...not huawei. I have nothing to do with the PRC! :)
