India, Nov. 7 -- More than 800 flights were cancelled in United States even as the flight cuts announced at 40 airports - including New York, Los Angeles and SanDiego - are set to kick in on Friday.

This comes after the Federal Aviation Administration ordered a 4 per cent reduction in flights at 40 airports across the US to cut traffic starting Friday, even as operations remain impacted amid the government shutdown.

Following the FAA order, several major airlines preemptively cancelled hundreds of flights scheduled for today, with the mandated cuts expected to increase to 10 per cent next week if the shutdown continues, CNN reported.
