Oh...not Hare, anymore.

Chicago's ORD, one of the world's busiest airports, is going through big changes to small planes.

American to outsource at O'Hare - chicagotribune.com: "American Airlines plans for the first time to outsource flights at O'Hare International Airport as it bolsters its summer schedule, the Tribune has learned.

The move is angering pilots of the airline and its American Eagle subsidiary, and is part of a broader reshaping of O'Hare operations that is causing passenger traffic and revenue to sharply decline.

Operating under the American Connection brand and subcontracted to regional carrier Chautauqua Airlines, the new flights will carry American customers to 15 cities scattered between Oklahoma City and Cincinnati.

American Eagle pilots have filed a grievance challenging the move, which they contend isn't allowed under their contract. But American disagrees and is pushing ahead."
