Flights delayed across US amid air traffic controller shortages as shutdown drags on

Nearly 50% of 30 busiest airports facing absences as staff are forced to work without pay and shutdown hits 31st day

Nearly 50% of the 30 busiest US airports faced shortages of air traffic controllers, the Federal Aviation Administration (FAA) said on Friday, leading to flight delays nationwide as a federal government shutdown hit its 31st day.

The absence of controllers on Friday is by far the most widespread since the shutdown began, with one of the worst-hit regions being New York, where 80% of air traffic controllers were out, the agency said.
