You do have a point that it could possibly be a first step in dismantling US in preparation of part 2 which would be the end goal of a merger with CO. (I personally do not hope that's the case for our sake and for the sake of US employees) Or it could just be ploy to get CO to the table.
But as I said, our MEC has gone public with the statement that no meaningful merger talks are underway with US. And this is where I disagree with you. Since the Master Chairman holds a seat on the board of directors, you are correct in thinking that he or she could not divulge any information with regard to a merger if one was actually being talked about in the board room. However, the Master Chairman can certainly say what is not being talked about. You can't get in legal hot water for talking about something that is not happening. So when they come out with "no comment," or worse... say nothing at all, that's when I get worried.
The fact is that our MEC has a proven track record of being VERY careful of what they say publicly, and rarely even make public statements like the one I posted. When they do, they have historically been 100% accurate. Thet were very specific in saying that the story has been confirmed as being speculative. So believe who and what you want. I for one will check back in about a month. But for those hoping for a UA/USmerger, I wouldn't hold my breath. It just doesn't make sense.
