Just curious, how do the logistics of this work? Presumably there is more than one person in LH's F cabin so are there multiple Mercedes waiting by the plane?
Not at the plane, but from the FCT/FCL there are indeed multiple S class Mercedes, Cayennes, Panameras driving F pax to the jetway gate or apron position. They will try to give you a private ride (Mrs. SFO and I have never had to share with anyone) but it doesn't always work. These pics are from MUC. LH has a veritable flotilla in the bigger FRA hub.
