WASHINGTON, April 10 (Reuters) - Major airlines are

asking the Biden administration to extend cuts to minimum flight

requirements at congested New York City-area airports through

October 2025, citing air traffic controller shortages, according

to a letter seen by Reuters.

Under minimum flight requirements, airlines can lose their

takeoff and landing slots at congested airports if they do not

use them at least 80% of the time. The waiver allows airlines to

not fly some flights and still retain slots. U.S. regulators in

September extended those cuts through October 2024.
