BTW I am not sure if this happens in the US as well but I've seen Jet employees escort "celebs / key guests" through security and boarding in India.
Once I was in security line at MAA and was tapped on the back by a Jet Lady to move out of the line so that a very smiling Nooyi (pepsi) could keep her bags on the cabin bag check. Similarly once on BLR-MAA sector had to wait for (who I found out later to be) Yesudas to go through.
But then on one other occasion rode the bus with Kapil Dev in BOM to boarding and he was just the usual guy. No jet escort.
