WASHINGTON, Nov 13 (Reuters) - U.S. airlines have cut

far fewer flights for Friday despite no change in a requirement

that they cut 6% of domestic flights at the 40 busiest American

airports, according to aviation analytics firm Cirium and

airline officials.

The Federal Aviation Administration late on Wednesday said

it would freeze mandatory flight cuts at 6%, and would not hike

cancellation requirements as previously announced. Cirium said

that after cancelling around 3.5% of total flights on Wednesday

Thursday, airlines have canceled just 1.4% for Friday.
