Authentic. Grammar and the like aside, as several others have posted, this "list" is out there. It has no basis in reality, just someone's wet dream. Again, shouldn't get worked up about it at this point. My advice is if someone shows you this list as anything other then amusement, you should simply laugh. This "merger" appears highly likely, but who controls it and when is still unknown. Even if it does occur, it's possible it may involve U itself being broken up. It's possible certain segments of U will be sold to others or even certain segments of AA. I don't think even the players know full well what they would have or want.

Will this be a work in progress or is someone formulating a finished product via a plan ?

If the former, it's even more likely it will morph and change as time goes on. It will take years to complete to one cohesive carrier and more then likely those who are clinging to such a list will have probably blown their brains out by then.
