I've had a few celebs on my flights. I generally don't gush or even make conversation though unless they initiate - I'd hate to have to be 'on the clock' all the time like that, so I leave them be.
Spike Lee - the elderly woman next to him, upgraded from coach, had NO CLUE who he was - even came up to me in the galley later and mentioned "what a nice young black man he is, so courteous!"
Olympia Dukakis - VERY impressive woman
Marion Jones - a little miffed that I wouldn't/couldn't upgrade her friend after we'd taken off, but otherwise nice.
George and Barbara Bush + secret service
the 'red dress lady' white house reporter that had been there forever - lovely woman
a few assorted congressmen but no 'major players'
yo yo ma - he bought a seat for his cello and couldn't remember if it was supposed to be window or aisle...I joked and said, "Well it depends, does your cello have more miles than you?" hehe
Destiny's Child
Cleveland Indians - sports charter...boy those guys are 'thirsty' after they lose!
Handful of NFL players - can't remember names.
Hrm...there have been others, but I can't recall. I'm told Sandra Bullock flies us often out of Austin...a friend had Bill Clinton on a flight. Another had Ashanti. An acquaintance had Christopher Reeve on board (only his second flight since his accident!). A pilot I know sat next to Christopher Cross on a flight...was told that he wrote "Between the moon and NYC" while in a holding pattern into JFK. ;-) Another co-worker talked about serving Pam Anderson and Kid Rock - said both reeeeked of pot, and she wouldn't speak directly to the FA's and they're weren't to speak directly to her...they had to 'go through' Kid Rock. (Puhleaze.)
Always interesting up there. :-)
