I also just flew with KQ from Nairobi to Amsterdam on their 767 and while not flying with them for several years, I must say they have kept their standard! It definately is a European standard airline, so you are going to have a pleasant time with them. Nothing special, but a competitive effort!
SAA is also a very high standard airline but I am sure KQ stands the comparison...
I haven´t heard the cause for the accident but let´s keep in mind that even Singapore Airlines just had a severe accident and yet, they are one of the best airlines in the world.
Have a nice trip!
