I saw Travolta in FLL once.
I was sitting in the restaurant with my student when a Gulfstream taxied up. It taxied really fast directly toward the restaurant and made a snap turn at the last moment.
My student said, "That guy really thinks he's hot sh--."
As we watched, a man with an entourage got off and walked in. Several minutes later, as they walked out to depart, the man signed autographs for the rampers.
It turned out it was Travolta.
