Battle for O'Hare? American expands Chicago route map

American Airlines revealed eight new routes from its hub at Chicago O’Hare, a service expansion that appears aimed at least in part at rival United. Seven of American’s eight new O’Hare routes are to small and medium-sized domestic markets, according to details spelled out Thursday by American President Robert Isom in a letter to employees. The eighth route will be an international route connecting O’Hare to Guatemala City. The new domestic routes from Chicago begin July 5 and will operate non-stop to Appleton, Wis.; Birmingham, Ala.; Boise; Colorado Springs; Greensboro, N.C.; Greenville, S.C.; and Ontario, Calif. The California route will be seasonal through the summer fall schedules. The new routes come on top of previously announced new service on American between Chicago O'Hare and Barcelona (seasonal); Bozeman, Mont. (seasonal); and Hattiesburg, Miss.<br/>
