WASHINGTON, Nov 16 (Reuters) -

Airlines anticipate the Federal Aviation Administration will

end 3% domestic flight reductions at 40 major U.S. airports

early Monday, easing restrictions imposed over air traffic

control safety concerns, sources told Reuters.

Late Friday, the FAA cut in half the flight-cut requirement

from 6% to 3% but airlines have not been complying with the

requirements. Carriers on Sunday canceled just 0.25% of flights

at those 40 airports -- less than normal cancellations --

according to Cirium, an aviation analytics firm. The FAA and

Transportation Department did not immediately comment late

Sunday.
