Empty A380
I was booked on an evening Air France from Singapore to CDG when they cancelled the flight in the afternoon due to mechanical problems. I was busy at work that day so I couldn't stay on hold to rebook on another airline. I knew several others on that flight and AF had booked them out that same night on other airlines. I got a notice that the original flight would leave in the morning so I just waited. The boarding area was nearly empty and there turned out to be no more than twenty people on that flight! I was on the upper deck and walked by row after row of empty business class seats. My entire section was empty. It was like being on a ghost plane but I loved it!
