Bill Murray was on UA3836 ORD->CHS on 2/15. My wife elbows me and says I think that’s Bill Murray! I was like no way he’s on a crappy CRJ200 but there he was in 2C. Super nice guy, he waited for his bag on the jet bridge with everyone else and was very gracious in chatting with people. Also ended up using the urinal next to me in the bathroom after grabbing our bags... and no I decided against chatting him up while in the middle of doing our business .
