Be careful what you wish for.
This is from Horton:
"For many years, I have publicly been a proponent of consolidation as one path to a healthier US airline industry. We have assessed many possible combinations in the past, including, of course, an acquisition of US Airways. In fact, last year, I approached my counterparts at other airlines about the merits of possible combinations. Since that time, as we embarked on the restructuring journey, I have held the view that it is best that we first put our own house in order before considering a complex and challenging airline acquisition. That is just common sense. But it is also prudent merger strategy, should we take that path, to assure that we begin from a position of greatest strength and stability. That has been our steadfast approach. It is no surprise that others have sought to disrupt our restructuring for their own benefit and contrary to the best interests of our company. This has not, however, distracted us from proceeding with a successful restructuring of American, and we are arriving at the appropriate point to carefully and objectively evaluate the range of strategic alternatives available."
If history repeats itself US would be pretty much dismantled by AMR.
