Dennis Tajer, a spokesman for the Allied Pilots Association (APA), said he expects planes to fly with more fuel than is needed to complete their journey when they travel from cities where fuel is more abundant into cities where supplies are tight.
Because extra fuel adds weight, planes may need to leave some seats empty, he told AFP, adding that "safety is the most important thing."
Besides working to conserve fuel, Dudley urged pilots to contact American Airlines dispatchers early "if it is necessary to land enroute" and noted that taking on extra fuel "will lead to a heavier aircraft when landing."
