Air traffic control staffing issues cause flight delays across U.S.

The Federal Aviation Administration said late Sunday that air traffic control staffing issues were delaying travel at airports in Dallas, Chicago, Atlanta and Newark as a U.S. government shutdown hit its 19th day

The Federal Aviation Administration said late Sunday that air traffic control staffing issues were delaying travel at airports in Dallas, Chicago, Atlanta and Newark as a U.S. government shutdown hit its 19th day.

By Monday morning, staffing issues at most of those airports seemed to have been resolved. A staffing trigger was in place in Philadelphia, which also affects traffic going into Newark Liberty International Airport in New Jersey.

It wasn't immediately clear whether this staffing trigger affected flight times.

As of early Monday, 846 flights within the United States had been delayed, according to FlightAware, but airports in Philadelphia and Newark did not top the list of delays.

The FAA said Sunday night that numerous staffing triggers had been received for the evening shift, and flights could also be delayed in Las Vegas and Phoenix because of air traffic control absences. Neither airport had a staffing trigger listed Monday morning.
