Just getting back onto the basic debate, I don't go too much with the argument of ascribing any "blame" to Spanish ATC.
There are plenty of places in the world where ATC is known to be sub standard - it's just part of the cards you are dealt with.
If Spanish ATC is known to be lacking in certain areas, wouldn't that be a reason for being proactive and loading more than a little fuel extra and/or perhaps allowing a little bit extra for diversion and/or making an early decision to divert?
Am not saying that it is excusable for ATC to be deficient anywhere and that we shouldn't attempt through all channels to lobby for improvement but surely it's part of the Captain's and operating company's remit to be proactive in all areas. (btw am not saying these pilots or even Ryanair, operationally, do not do so but making a general point).
