The FAA said Monday afternoon that the ground delay will be in effect from 3:30 p.m. CST until 8 p.m. CST. It impacts flights coming in from 1,400 nautical miles. The FAA said departures to AUS are delayed an average of 37 minutes.

"Due to security" was the FAA's National Airspace System Status explanation for issuing the ground stop for DCA. The ground stop was issued at 1:43 p.m. on Wednesday and was scheduled to stay in place until 3 p.m. The probability of an extension was "medium," according to the FAA.

Officials there said a staffing shortage was to blame for delays Sunday of up to three hours and a ground stoppage.

Airport officials continue to urge travelers to check flight statuses and contact airlines for updates. Sunday's delay marks marks the fifth ground delay at ABIA since last month, and the second one in three days after a ground delay was issued on Friday.

Travelers are bracing for canceled flights and extensive delays after one flight’s engine issue prompted a ground stop at John F. Kennedy International Airport Thursday. Bad weather is doing the rest.
