Recently released September airline traffic data shows that AMR, parent company of American Airlines, continues to struggle. American had a terrible month, experiencing problems with seats coming loose on some flights, and experiencing more delayed and canceled flights with more pilots calling in sick. Not surprisingly, AMR's total traffic dropped 2.8% in September, with domestic traffic falling 7.1%. One bright spot for the struggling airline was a 4% uptick in passenger revenue per available seat mile, which rose due to more effective international joint ventures.

Still, this has been a terrible month or so for AMR, which is trying to exit bankruptcy as an independent airline. One of its biggest obstacles to doing that, the reluctance of its pilots' union to agree to a deal, is showing no signs of changing despite the fact that the two sides have resumed talks. In the video below, analyst Brendan Byrnes explains why he believes that the most likely outcome is AMR merging with US Airways, and why most long-term investors should stay away from legacy airline stocks.
