I aint see no celebs, but last time i flew my sister and her husband had a couple guess passes. It was great. Still pretty crowded, but especially once they flew out and i snagged a personal booth.... whewweee it was worth it. At the price of nothing.
I dont fly often enough to give a dam, but for people who fly regularly it might be worth checking. My brother in law isnt rich afaik, but he definitely has a well paying job and is responsible. Travel is their big thing, so I see how it makes sense for them.
