LOUISVILLE, Ky. (WDRB) — As the partial government shutdown continues, TSA agents across the country are working without pay, leading to growing travel disruptions and frustration for passengers.

While security lines at Louisville Muhammad Ali International Airport remained relatively smooth Wednesday, the impact of staffing shortages is being felt nationwide.

David Castelow experienced those disruptions firsthand while trying to return to Louisville after multiple flight cancellations.

"Since Sunday, I’ve been stuck," Castelow said.

He described long waits, crowded terminals and confusion as delays mounted.

"They finally got us on a flight to Ft. Lauderdale. Got to Ft. Lauderdale, people all over the place sleeping — I was about to drive back to Louisville, I was so frustrated," he said.

The Transportation Security Administration is already short-staffed, with hundreds of workers calling out during the shutdown because they are not being paid.

Though Louisville is avoiding major delays so far, travel experts warn the ripple effects are spreading.

"Definitely there is a butterfly effect," said Amy Thomasson, an Indiana-based travel advisor. "Even though TSA wait times aren’t affected at Louisville, wait times at other places are. People are getting their flights canceled, and then that affects other things."

Thomasson said recent fluctuations in jet fuel prices tied to overseas conflict added to uncertainty in the travel industry, though prices recently stabilized.

Her advice to travelers is to stay calm.

"Don’t panic buy and don’t panic cancel," she said. "If they are able to, just hold off and wait, and we are going to see what happens."

Some passengers said their experience in Louisville remained manageable.

"TSA was fine," said traveler Lien Rios, who flew in from Orlando. "There was a bunch of people, it was fully packed — all the lines were open. It was working just fine."

Despite smoother conditions locally, Castelow said the ordeal took a toll.

"Oh man, I want to get into my bed," he said. "I don’t mind staying in hotels, but I want to get in my bed."

Airport officials said the busiest travel times in Louisville are typically early in the morning, around 4 and 5 a.m. Travelers are advised to arrive about two hours before their flights — compared to the three hours recommended at larger airport hubs.
