WASHINGTON, Nov 9 (Reuters) - Airlines canceled more

than 2,700 U.S. flights and delayed more than 10,000 on Sunday,

the most disruptions on a single day since the U.S. government

shutdown began.

Major airlines were dealing with a third day of

government-mandated flight cuts along with rising air traffic

controller absences, which has caused thousands of delays and

cancellations. Delta Air Lines ( DAL ) was especially hard hit,

cancelling or delaying 52% of its mainline flights on Sunday.
