I just flew BA 001 yesterday 6/29 and Jon Bon Jovi was in row 3 (didn't see who would have trumped him in rows 1 and 2. I think he did a concert in Hyde Park the night before. When I was walking to the tube station to go to LHR (since I spent all my $ on the flight...), there was a crowd waiting outside the Mandarin Oriental, and based on a few t-shirts, I figured he was entering/leaving the hotel. It didn't occur to me that he'd be on my flight.

Nevertheless, he seemed pretty much left alone by the pax, and even wandered throughout the cabin holding his baby (who had his own seat BTW...)
