Airports are still recovering from the fallout of the DHS shutdown that resulted in a shortage of transportation Security Administration (TSA) officers - and some are now changing their advisory messages to travelers.
John Glenn Columbus International Airport in Ohio is cautioning passengers to arrive just 1.5 hours before their flights depart.
"Early morning travel PSA, 90 minutes before departure is the sweet spot," the airport posted on X on Thursday.

"Showing up too early creates those first-wave lines," the post also said. "Even when lines stretch to ticketing, waits are usually [about] 45 mins."
The airport also attached a graphic of suggested arrival times for flights starting at 5 p.m. through 12 p.m.
Austin-Bergstrom International Airport in Texas wrote on X it's expecting over 30,000 travelers to be processed by TSA on Monday.
"There is no need to line up more than 4 hours before your flight, as this causes congestion in the lines for those flying out sooner," the airport wrote.
