LITTLE ROCK, Ark. -- Flight delays, strained staffing and drops in tourism spending are surfacing nationwide as the federal government shutdown continues, and long-time travel professionals in Arkansas say the situation is worsening.

The U.S. Travel Association estimates the industry has already lost more than $1.7 billion. TSA agents and air traffic controllers are reporting to work in smaller numbers as many look for ways to make ends meet without guaranteed pay.

Erma Bridges, who has run a travel agency in Little Rock for 40 years, says that financial strain is showing up in airports.

"But now that they're not getting paid, they're not coming to work," she said.

At Clinton National Airport, operations haven't ground to a halt, but staffing levels are unpredictable, especially at airline counters and security checkpoints. Bridges says arriving early isn't just smart -- it's necessary with fewer hands on deck.

She encourages passengers to pad their schedules and think ahead in case lines move slowly or flights shift.

"Make sure that you're well prepared, get to the airport early, make sure to bring some snacks and games for the kids," Bridges said.

The shutdown's effects stretch well beyond airports. Theme parks, hotels and restaurants across the country are seeing fewer bookings.

Bridges says this shutdown is cutting deeper than those in the past because air travel has grown significantly over the decades. More people are affected when staffing thins, schedules shift and services are scaled back.

Travel experts warn that, if the shutdown continues, connecting flights and overnight stays could become increasingly unpredictable, even in cities that haven't seen major disruptions yet. Passengers are being urged to stay flexible, monitor updates and prepare for longer waits as the situation evolves
