This will probably never be replicated, so I should really ask for a badge from the airline. I recently flew KLM AMS-MVD direct, a route that doesn't exist. It was bound for EZE but diverted due to almost 0 visibility from fog.
After landing on the tarmac, the plane sat in a waiting area while I asked the cabin chief to let me off. Everyone agreed but the airline and airport control both said no at first. After some negotiations between the pilot and ground control (and noise from me), success! First off the plane and onto the bus, no sweeter feeling as my final destination was MVD anyway
