Travelers can earn a 50 percent mileage bonus for US Airways Dividend Miles or American AAdvantage when traveling on the other airline through March 2, 2014.
For US Airways members, you will get 50 percent more miles when traveling systemwide on American Airlines, American Eagle and American Connection operated flights and crediting your flight to US Airways Dividend Miles.

For American AAdvantage members, you will get 50 percent more miles when traveling systemwide on US Airways, US Airways Express and US Airways Shuttle operated flights and crediting your flight to American AAdvantage.

The bonus miles are award miles and will not count toward elite status, so keep that in mind when choosing to take advantage of this deal. Also worth note is that if you are an elite member in one of the programs, you might get more miles by sticking with your current program since the 50 percent bonus miles are based on the base miles earned, not elite flight bonus miles.
If you have already booked a flight between Jan. 13 and March 2, 2014, you can get the bonus as long as you register for the promotion at one of the links above.
