Was booked for Thursday night on LH 731 HKG to MUC and onward to HAM.
In a first attempt called the HKG LH hotline which proved useless as they were unwilling to do anything until the flight would officially show as cancelled in the system. Their recommendation was to call back Monday/Tuesday when they have more info but we all know how that would have turned out...
So I called the German MM hotline and was rebooked to SR within five minutes. Almost identical times and higher booking class - very happy.
Let's hope all goes smooth from here...
