The Vignelli identity was only replaced in January 2013 as part of a rebrand of American Airlines by Futurebrand.
American Airlines Group says more than 60,000 staff across the company voted, with 52 per cent opting to keep the new design rather then reverting to the Vignelli option.
Chief executive of the American Airlines Group Doug Parker made the decision to allow staff to decide on the fate of around 1,500 tail fins.
Parker is reported to have said that while repainting the entire plane would have been too costly, the employees could chose the tail-fin design.
This could have resulted in a composite design with two logos appearing on the same plane.
