On a recent LH flight from FRA I was addressed by name by one of the cabin crew during the meal or drink service. I have no direct staus with LH but am an Aegean *A Gold.

And the overhead lockers in LH have notices saying they are for J passengers only.

And at the gate there was pre-boarding scrutiny of your boarding pass so when priority boarding commenced there was no waiting. Alas, spoilt by having to scan your boarding pass at a barrier which created something of a queue.
