It has been reported that managers at American Airlines and leaders of the pilots union agree carrying less fuel isn't a safety issue under routine circumstances.

The two sides digress, however, when it comes to unexpected variables such as flights being diverted while in the air.

Dennis Tajer, an American pilot and spokesman for the Allied Pilots Association, said, "It's being touted as a corporate efficiency program, but perhaps it has gone too far. It has the ability to affect the margin of safety and reliability. That is our concern."

American's strategy of carrying less fuel is aimed at reducing fuel purchases and also the amount of weight each plane carries. A plane carrying a lighter fuel load actually burns less fuel, The Chicago Tribune reported on Sunday.

American, to achieve its goal, has given the job of figuring out how much fuel each plane carries to airline dispatchers. The task has traditionally been performed by the pilot.

Planned fuel loads would include about 90 minutes of reserves, which would be trimmed down over the course of the year, The Tribune has said. The FAA requires a 45-minute reserve. (With Inputs from Agencies)
