I have seen more celebs on the LAX-JFK-LAX flights than the entire time I have lived in LA.

Recently:
LAX-JFK
Alec Baldwin and Richie Sambora
The guy who played the magician brother on Arrested Development
The guy who played the black president on 24. He was very nice.

I've seen a bunch of other celebs but can't remember their names or what shows they were on.
