MUC - LGG is the only real new route for MUC, which is a surprise indeed.
MUC-BRN has been served over the past two decades by various airlines and for a good couple of years by Lufthansa affiliates feeding the MUC hub. Currently it is served by Skywork twice daily which proably will not last long if BM can offer a LH code-share.
MUC-RTM is taken over from LH Cityline.
Reminds me a little bit of the times when Debonair set up shop at MUC and operated quite a few route for Lufthansa in the late 1990s.
