The government shutdown is now disrupting travel plans for thousands.
Air traffic controllers have been working without pay since October 1, and an increasing number of them have been calling in sick as the shutdown extends into its second month.
These staffing shortages prompted the Federal Aviation Administration to mandate a 10% reduction in flights at 40 of the country’s busiest airports, forcing airlines to cancel flights.
That started with a 4% reduction on Friday. It will ramp up to 10% by November 14.
Some 750 flights have so far been canceled as of 6 a.m. ET on Friday, according to data from Cirium, an aviation analytics firm. Only domestic trips are directly affected by the FAA mandate, with major airline hubs bearing the brunt of the impact.
