NEW YORK (TheStreet) -- Shares of American Airlines (AAL) - Get Report were advancing in mid-morning trading on Friday as the company prepares to transition all its pilots and planes to one unified flight operating system this weekend, the Wall Street Journal reports.

Since its merger with US Airways in 2013, the company has used three separate operating systems for its combined 15,000 pilots and 1,500 aircraft.

US Airways and American pilots and planes have also flown separately under their pre-merger designations.

The transition this weekend will allow the Fort Worth-based air carrier to schedule all flights under one system. American will also have the ability to mix and match US Airways and American aircrafts and pilots, providing additional flexibility and efficiency.

American's Chief Information Officer Maya Liebman said there could be "minimal delays" this weekend if the switch-over creates problems, but noted that customers won't feel the impact, the Journal reports.

But the Allied Pilots Association, the company's pilots' union, said that the move "poses a significant challenge to our airline," according to the Journal.

Separately, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.

TheStreet Ratings rated this stock as a "hold" with a ratings score of C-.

Among the primary strengths of the company is its respectable return on equity which we feel is likely to continue. At the same time, however, we also find weaknesses including unimpressive growth in net income, generally higher debt management risk and poor profit margins.
