David Coulthard - had him twice on board - so nice chap, a real gentleman
Jean-Claude Van Damme - was in economy on a flight from BRU to NCE some years ago, during the Cannes Festival. He tried whatever he could to be upgraded in business, but it didn't work
Made me open all the "tax free" items during the flight, and eventually didn't buy anything. Guess he was under the influence of any illegal substance. So arrogant ! His wife was nice though.
