I think not yet mentioned here: FR will start flying from Leipzig/Halle LEJ to STN and CIA (this is Leipzig proper - not Altenburg). This is a good move at LEJ has no London flights at all (!) while it has excellent infrastructure (train to Leipzig central takes about 20min). LEJ was one of the German reunification projects which where too enthusiastically planned, they were even hoping to become some kind of LH hub. Current main user is DHL for cargo. Note the ICE from Leipzig to central Berlin takes only some 1:15, while the train from SXF to central Berlin takes already some 30min. But I don't think this will mean moving capacity from SXF to LEJ ahead of BER opening next June.
