I recently took a flight on the A380 (the third one that just went into service) and wanted to take a quick look at the cockpit, while parked at the gate. When I asked, I was told that SQ disallowed passenger access to the cockpit at any time, for "security reasons".

Any idea when this policy was implemented? I would have been fine looking from the outside, but it was fairly clear the friendly (but robotic) F/A was not going to accommodate me. Since flight crews are busy and I am sure lots of people want to look at the A380 cockpit, I guess the policy makes sense, but I was still a bit disappointed.
