It seems to me that a large majority of growth in the GCC region (and not limited only to the airline sector) is ego driven. Easy money (petro-dollars) national pride and personal egos have created airline projects which I doubt are anywhere near profitable (but as one well-known airline CEO said a few years ago-- profit is not the most important thing) or sustainable.
However in the meantime, seems everyone is having a good time.
