American Airlines’ Executive Vice President-Marketing Daniel Garton was tapped yesterday to succeed Peter Bowler as president and chief executive officer of American Eagle. At the same time AMR also reiterated its intent to evaluate the possible divestiture of American Eagle. Before his departure, Bowler reported that American Eagle, which flew 16 million passengers last year coming in at number two in the industry behind SkyWest, was finally growing again “and playing a very central role in American’s corner-post strategy” at Miami, New York, Chicago, Dallas and Los Angeles.
