A look at arrivals and departures from Hartsfield-Jackson Atlanta International Airport on Friday afternoon showed several delays and a few cancellations as a mandated reduction in flights began its first day.

Delta Airlines said in an update that it expects the “vast majority” of its flights not to be affected by the government’s decision and go ahead as scheduled. While complying with the government directive by reducing its domestic flights, its international flights won’t be affected.
