- Wait times have dropped sharply at several US airports since TSA agents started receiving paychecks.
- Atlanta previously faced lines up to four hours, but these were down to a few minutes on Tuesday.
- Baltimore airport on Monday said it was seeing a "return to normal."
It looks like the worst of the airport chaos is coming to an end.
Wait times at security checkpoints have plummeted at Atlanta's Hartsfield-Jackson International Airport, which was one of the hardest hit by Transportation Security Administration staffing shortages.
While last week it warned passengers of four-hour lines, its website listed waits of less than five minutes at all checkpoints just after 6:20 a.m. ET.
The airport had previously suspended this feature during the peak of the staffing shortages, instead displaying a message telling people to expect four-hour waits in line.
Delta Air Lines' main hub, Hartsfield-Jackson, is also the world's busiest airport by passenger numbers, handling over 100 million last year.
It's an especially busy time for flying, too, as people travel for Spring Break.
In an X post, the airport thanked passengers "for their continued patience during the recent challenges caused by the federal government shutdown and its impact on our federal partners."
It added that passengers were encouraged to arrive at least two hours before a domestic flight, or three hours for an international flight, which is the standard advice.
Atlanta is not the only place where TSA wait times have dropped sharply this week. Houston's George Bush Intercontinental Airport also suffered from four-hour wait times last week. But on Tuesday morning, its website showed lines of a maximum of 30 minutes.
New York's John F. Kennedy and LaGuardia airports have also restored their websites' estimated wait-times feature. Lines at JFK were the longest of any airport monitored by Business Insider, with a wait of 43 minutes, while Newark had 20-minute lines.
Baltimore airport, which handles around 25 million passengers annually, said on social media that it had seen a "return to normal" on Monday.
"The normal, quick and efficient checkpoint operations we're known for have returned today," the airport said in an X post.
We know the last few days have been difficult.

Lines began to improve after President Donald Trump signed an executive order on Friday to pay TSA agents, bringing many back to work.
The workers hadn't been paid since mid-February, when a partial government shutdown began. Up to 11% of TSA agents called out of work on the worst-affected days.
While the Senate approved a deal early Friday to fund most of the Department of Homeland Security, it was opposed by Republicans in the House of Representatives who want more funding for Immigration and Customs Enforcement. Democrats want ICE to be reformed in the wake of January's violence in Minnesota.
TSA agents began receiving paychecks on Monday, though the shutdown is still ongoing. Plus, Congress has gone on recess for two weeks, while the two parties remain at loggerheads.
