Dangerous storms and the TSA pay freeze made traveling a nightmare for flyers across the country Monday, with thousands of flights canceled and hours-long security checkpoints paralyzing major airports.

And even if the weather clears later this week, there’s no sign that Democrats are going end their blockade against funding the Transportation Security Administration and other key parts of the Department of Homeland Security.

Flights at Hartsfield-Jackson Atlanta International Airport in Georgia and Charlotte Douglas International Airport in North Carolina ground to a halt, while George Bush Intercontinental Airport in Houston was experiencing ground delays thanks for the extreme weather, Transportation Secretary Sean Duffy said on social media Monday morning.

More than 3,600 flights were canceled, while another 6,800 flights were delayed, according to the flight-tracking site FlightAware.

The Midwest was dealing with blizzard conditions while the east coast faced severe thunderstorms expected to bring volatile winds and flooding, according to AccuWeather.

About 200 million people were being affected by the extreme weather, the weather service said.

Flyers whose plans weren’t kiboshed by the weather were still hit with massive security lines as a partial government shutdown dragged on, halting pay for TSA workers.

The debacle occurred because Democrats have blocked the passage of partial funding the DHS after the after the fatal shootings of Alex Pretti and Renee Good in Minneapolis by federal immigration agents.

“Storms aren’t the only thing interrupting travel this week. The Democrat DHS shutdown has TSA officers working without pay, with 300+ already quitting the job entirely,” House Majority Whip Tom Emmer wrote on X.

“Staffing shortages are causing mind-blowing wait times at airport security, and Democrats are 100% to blame.”

The two sides of the debate are divided over Senate Dems’ push to ban immigration agents from wearing masks and to require them to wear body cameras and show identification during law-enforcement actions.

The TSA funding, under the Department of Homeland Security, lapsed Feb. 13.

Airport screeners — the vast majority of whom make less than $50,000 per year — missed their first full paycheck earlier this month.

Video footage showed passengers in line Monday morning outside Austin-Bergstrom International Airport in Texas as they waited to get through security.

Staff at the airport had been advising travelers to show up at least two and a half hours before domestic flights, though security lines were back to normal by late morning, according to Austin-Bergstrom’s X account.

Staff at Louis Armstrong International Airport in New Orleans told passengers to show up three hours early “due to impacts from the federal government’s partial shutdown.”

Democratic Pennsylvania Sen. John Fetterman sided with the GOP, telling Fox News, “It was always the wrong thing to shut out government down.

“It’s gonna continue to deteriorate at our airports and security all around our nation, as well, that’s never gonna produce the kind of reforms for ICE and make those kind of changes because we all agree it was never gonna be about that, it was all about what parts of my base would demand,” he said Monday.

House Speaker Mike Johnson accused Democrats of “holding TSA agents hostage and putting American lives at risk.

“Democrats would rather PROTECT criminal illegal aliens than the American people,” he wrote on X.

But the Senate’s top Democrat, Minority Leader Chuck Schumer of New York, has argued his party just wants ICE to “behave like police departments” in the country.

“We know the American people are on our side. We know that the only thing Republicans need to do is stay out of the way and these programs will be funded today and problems at the airports will go away,” Schumer said during a floor speech last week.
