American Airlines will merge its flight operating systems this weekend, a year after merging its reservations systems following the 2013 merger with US Airways.
American Airlines introduced a new top management structure on Monday and new uniforms Tuesday. Shares are up 41% since June 27.
Southwest Airlines stands alone in that it doesn't charge for first and second checked bags and continues to hedge fuel costs.
Airlines lost out in their previous bid to have air traffic control spun off and privatized, but they are not giving up.
