Spokesman Phil Gee says the movie systems weigh about 500 pounds each, forcing planes to use more fuel to get around the country.
Jet fuel costs have skyrocketed in recent years, slashing profits and leading to thousands of layoffs and flight cuts throughout the industry.
Gee says US Airways will cut the movie systems from about 200 aircraft. But it will keep movies in its widebody aircraft for international flights and trips to Hawaii.
US Airways says it will test a lighter, seat-back TV system later this year. However, Gee says a new entertainment system is a long way off.
