Haha, that was not too long ago, because I've done this flight too once or twice, in fact I distinctly remember staying on the plane while at SKG once, I can't really remember if we were all asked to deplane on the other occasion, due to the necessary refueling that had to take place (I think that was the case). At the time I took that flight, there actually also existed a direct ATH-DUS A3840 flight, but I took the "detour", because it was way cheaper!
