The first flight of Lufthansa Group member Eurowings from Berlin (BER) to Dubai (DXB) has started.
I wrote a post about this and news from Eurowings CEO Jens Bischof about this in the thread "Unofficial Berlin Brandenburg (BER) Airport thread", here is a link to that post:

I think that the flights will probably be a success. Emirates is currently not allowed to fly to BER (because the federal German Government wants to protect Lufthansa and their hubs in FRA and MUC), so the Eurowings flight is often the best option to travel between BER and DXB.
