I'm not a pilot (yet)
But i'm almost certain that no-body is allowed to enter a flight-deck whilst in UK airspace. Not too sure about the rules for off-duty Pilots, Cabin-Crew and Engineers, but for Pax, it's a no-no
Nearly every UK airline has banned Jumpseat rides, regardless of where their aircraft are in the world.
Never the less, many European carriers still allow Jumpseat trips, not too rare i don't think, so we're all still in luck
I would jump at the opportunity to sit in the Jumpseat for a flight!
