Onur Air not too popular in the Netherlands just now, and a close watch on them from the IVW
Subchartered Tristars used (one on Sierra Leone register, so not welcome in UK) being frowned upon, Dutch have a downer on the Tristar anyhow following issues with Portuguese registered aircraft last summer...
Another problem with a Onur Air A300 at AYT last weekend further compounds the issue the Dutch have...
From what I can tell, lots of media noise in the Netherlands about Onur air, thus blowing the issue up even more.
