DENVER — The federal government shutdown resulted in staffing issues at several airports across the country Monday, including Denver International Airport. 

A Federal Aviation Administration advisory issued Monday said flights to DIA were being delayed an average of 40 minutes due to staffing. As of 8 p.m., more than 570 flights to and from the airport had been delayed Monday, according to FlightAware.

Transportation Secretary Sean Duffy said Monday that the shutdown is putting more stress on air traffic controllers who already have an extremely stressful job, as well as threatening a program that small communities rely on to help subsidize airline service.

Controllers are expected to continue working without a paycheck, Duffy said, so they are now worried about how to pay their bills in addition to worrying about keeping flights safe. And there have started to be instances of controllers calling out sick, leading to delays at several airports Monday.
