I remember sitting in the main Sky Club lounge at Detroit maybe two years ago, when Virgin Atlantic was still flying to/from Detroit. I saw the actor Jon Voight escorted to a corner in the back of the Sky Club by a Virgin Atlantic staffer. She asked if he wanted anything to drink and she fetched him a glass of wine, but then as now the bar in Detroit is self-serve. She came and fetched him when boarding was ready to commence.

I don't know if this was part of a special service because I've seen the governor of Michigan fly Delta two times and never receive an escort from either Delta staff or airport staff. Both times he has been in the main Sky Club lounge in a corner with a staffer and a security detail.
