Not quite in point, but I am a fairly regular passenger with KLM from Amsterdam to Kilimanjaro. For the last couple of years the flight has been flown by a 777. I notice that my flight next year is scheduled for an MD11. I was just wondering why the change? It seems the MD11 carries slightly fewer passengers but in my ignorance I would have thought that a 3 engined, older, plane would be more expensive to run than the 777.
I've no particular worries about the MD11 and some reviews I have read suggest it is a more comfortable vessel than the 777.
