Going OT here, but LH only 'lends' staff to SK. I've seen the SK duty manager turn away the second GA when the gate opened saying 'oh, we don't need two'. BTW, I was at the gate early because the flight was oversold and I was standing by.
SK (like some other *A partners in MUC T2) doesn't use LH for everything in FRA and MUC, the ground handling is done by Avia, and there is a SK duty manager for the day overseeing the handling of all SK flights that day, but he/she usually doesn't stay at the gate.
