Flight disruptions continued into Sunday, following significant cancellations and delays on Saturday. The Federal Aviation Administration (FAA) limited operations at 40 major U.S. airports due to ongoing staffing shortages amid the longest government shutdown in U.S. history.

As of 5:30 a.m. ET on Sunday, over 1,100 flights had been canceled nationwide, according to FlightAware. On Saturday alone, 1,521 flights were canceled, and more than 6,400 experienced delays. These numbers exceeded Friday's cancellations, which totaled 1,024. Since Friday, more than 3,700 flights have been canceled, and major disruptions are expected to persist through Sunday.

The FAA reported over 40 air traffic control staffing triggers at facilities across the country as of Saturday night. Transportation Secretary Sean Duffy stated in an interview that the FAA would not reduce international flights, as doing so would breach international agreements with other countries.

Travelers are advised to check their flight status and prepare for potential delays as the situation evolves. The FAA continues to address the staffing challenges affecting air traffic control operations across the nation.
