I just came across an interesting thought - all of the current Rimowa kit-equipped airlines happen to be part of Star Alliance.
Is it some sort of conspiracy? Why don't SkyTeam or Oneworld airlines give out the Rimowa kits? Yes, there's Tumi and Emernegildo Zegna and others being given out, but none has quite the cachet of Rimowa.
Maybe it's a Lufthansa influence?
