This afternoon, American announced its intention to spin off its American Eagle unit click here. Given the talk surrounding the company to consider spinning off AAdvantage, American Beacon Advisors, American Eagle and its maintenance unit, this announcement should come as no surprise.

Calls for American to spin off AAdvantage were first made by Reykjavik-based FL Group, which owns 9.1 percent of American in September. All US carriers, and not just American, are considering means to respond to increased shareholder pressure as airline shares have significantly underperformed the Standard & Poor's 500 Index this year.

One might say that AA is considering the divestiture of a regional carrier late in the cycle when growth has slowed considerably. On the other hand, if you believe that the regional sector of the US airline industry is not immune from consolidation, it just may be the right time to participate in the purchase of a carrier with a $2+ billion revenue stream that American says will remain intact as the parent plans to maintain all current feed provided by Eagle.

That revenue stream and an increased capital base will certainly have some attraction to regional sector’s biggest players: Republic, SkyWest, Pinnacle and others looking to assure their survival as its sector of the industry matures as well. American suggests the transaction will be a 2008 event with all the necessary caveats. No details have been provided on a deal structure other than a blank whiteboard.
