US AIRPORTS — More than 10% of Transportation Security Administration agents nationwide did not show up for work on Sunday, according to a Department of Homeland Security spokesperson. The absences occurred as the partial federal government shutdown has halted funding for the Department of Homeland Security, leaving TSA agents unpaid.

Over 300 TSA agents have quit since the start of the shutdown. The staffing shortages have created delays at major U.S. airports across the country.

Atlanta's Hartsfield-Jackson International Airport experienced disruptions, with over 37% of TSA agents calling out of work on Monday, according to a Department of Homeland Security spokesperson. On Tuesday, the main checkpoint for international travelers at the airport had lines up to 100 minutes long.

"We are seeing increased congestion caused by domestic travelers attempting to bypass lines in the domestic terminal," Hartsfield-Jackson International Airport said in a post on X. The next morning, the main domestic checkpoint at the airport had wait times of over an hour, while the international checkpoint had no lines.

Houston Hobby Airport also faced staffing problems, with 55% of TSA agents calling out of work on Saturday, according to a Department of Homeland Security spokesperson. Earlier this month, the airport saw TSA wait times of three hours. By Wednesday morning, the airport's website showed TSA wait times of 8 minutes for standard screening and 7 minutes for passengers with Pre-Check.

John F. Kennedy International Airport had the second-highest rate of TSA agent call-outs since the start of the shutdown at 21.4%. On Wednesday morning, TSA checkpoint wait times at the airport were over 30 minutes at Terminal 8 and under 10 minutes at Terminals 1, 4, and 7.

Atlanta's Hartsfield-Jackson International Airport reprimanded domestic passengers for attempting to bypass lines, which caused congestion.
