The National posted an interesting article a couple of days ago regarding the lack of available airspace in the Gulf, due in part to 60% of it being reserved by governments for purposes other than civilization aviation, and also to regional aviation developing fast and adding on to the traditional North (Europe) - South (Asia / Oceania) traffic.
At the end of the article, IATA also takes an unrelated dig at European governments. Their message: stop taxing aviation so much and instead spend a lot more on air transport infrastructure. A bit unusual, and somewhat ill-informed. As if the only reason Dubai is so popular a connecting point is because they were willing to build a big airport.
