Someone's being doing a lot of preparatory work behind the scenes by the looks of it. Not a bad start to Airbus's year.
It's interesting to think what might happen in the (hopefully) happy future where Iran is comfortably reintegrated back into world society and everybody is friends again. Emirates, Qatar and Etihad are busily setting themselves up as superhub-centred airlines in Dubai, Doha and Abu Dhabi. Their geographical position gives them unparalleled single-hop access to a very large fraction of the world's population. And of course, Iran is in the same neck of the woods, as is Turkey. Turkey are already planning a major new airport to allow their airlines to also become very superhub-ish. And there's plenty of hydrocarbons locally to fuel it all.
So in the future we might be seeing some monumental competition between five airlines all located within a couple of hours of each other. That could seriously change whatever passes for the current global airline industry status quo.
Ok so that's a looong way in the future, but other airlines are going to have to start planning on the assumption that what I've outlined above may one day happen.
