I recall reading that BA and other non-US airlines still allow cockpit visits during flight.

Has anyone done this with BA since 9/11, and what is the best way to request it from the Captain without coming on too strong, or giving the wrong impression on my intentions?

I'm flying a 747-400 in First Class to London from the states this week, and then back on the Concorde. I'm also a certified pilot (of the Piper/Cessna type), so I would love to witness a landing.

Suggestions appreciated.
