I would look at this article as biased. A lot of airlines have slowed down the renewal of the fleets in regards to the lower oil prices. If you put out such an article without showing numbers and dates, I look at it as an opinion piece rather than facts.
This newspaper 'De Telegraaf' is indeed biased when it comes to AF/KL. They were always negative about AF, and have spread many false rumors about AF having plans which would result in the demise of KL.
Looks like KLM will receive less new aircraft in the nearby future as Air France wants to shift some capacity to its upcoming LCC 'Boost'.
This journalist (Yteke de Jong) has a horrible track record when it comes to reporting about KLM and/or AMS. If she is the only source (as in this case so far) it's best to ignore, or at least add "rumour" to the title, as more often than not it turns out to be completely false.
Wasn't the original plan that KLM receives a number of A350s??
That is no longer mentioned in the article. This is why I have the feeling that KLM will get the Boeings as planned, but the A350s will go to Boost. Maybe not even the worst decision in terms of commonality at KLM (not having a small Airbus sub-fleet anymore once the A330s are withdrawn from service...).
I heard rumors that the A350 isnot going to join KLM's fleet. If they are not going to be replaced with B787 than that will mean a reduction in capacity.
The reports of KL not getting any A350s are 2 years old. I'm quite sure this scenario was seriously contemplated. But KL's CEO has since repeatedly said KL was to receive A350s, the first in 2020.
And indeed KL needs the A350s to finalize the retirement of the 747. The 787-10 would replace the A333s and one or two 747s, and the remaining 789s on order are not enough to replace the remaining 747s.
When it comes to replace the 77E at KL (this is still quite some time away), I'm sure KL will order more A350s than the 7 they now have on order.
