KQ definitely has a code share operation with KLM. You can book KLM from Amsterdam to Dar/Nbo and you are just as likely to get a KQ flight. And vice versa if you book KQ you might be lucky and get KLM.
I'm still curious about the legalities of transporting a body without prior permission across international boundaries. The report doesn't say what nationality the deceased man was, but this is a Kenyan aircraft from Dutch territory to Tanzanian territory. What does one put on the death certificate as to where the man died? Kenya/Holland/Tanzania/over Europe somewhere? And I really thought there were some pretty strict regulations governing medical emergencies on board an aircraft. I can't quite understand how or why the crew made the decision to continue the departure/flight with an obviously ill person on board.
I can however well imagine the consternation of the crew and passengers having to deal with a corpse!! What a flight!
