When was the HAM route axed by Lufthansa?
Apparently the only sustainable routes to Germany are DUS, FRA and MUC. Not sure about BER in the long term.
HAM, BRE, FMO, DTM, MGL, CGN, STR, NUE, LEJ have all been tried and did not last.
Noted by the way that CGN is looking for an airline to operate to LCY. The last airline that tried was Augsburg Airways in the late 1990s.
