In September I was flying from Hamburg to Frankfurt with LH Airbus 320. While check in I asked the staff if it is possible to enjoy the flight on the jumpseat in the cockpit or even visit the cockpit during flight. I flew C-Class, so the distance from my seat to the flightdeck was not very far. The told me after Sep. 11 this is not possible any more, but they offered me to have a look inside after arrival in FRA. But of course the crew had no time for me.
Now I fly KoreanAir and KLM next time. Hopefully I have the chance for a visit. How other airlines handle this question ? Any experience ?
