Houston’s airports have been pummeled by the government shutdown with three- to four-hour security lines over the last few days — and the worst TSA absentee rates in the entire country.

Hobby International Airport topped the leaderboard with a staggering 47% of its TSA workers calling out Saturday, while George Bush Intercontinental Airport saw about 42% of its security staff take the day off, according to CBS News.

Meanwhile, New Orleans’ Louis Armstrong International Airport saw a 34% call out rate, Atlanta International lost 33%, and New York’s JFK also saw about 33% of its TSA staff stay home.

In total, 11.5% of TSA workers called out across the US on Saturday, while about 450 workers have quit altogether since the partial government shutdown began on Feb. 13, according to the TSA.

Most TSA workers have gone largely without pay since then — leading directly to the unbelievable no-show numbers.

The shutdown has persisted as Democrats and some Republicans have refused to fund the Department of Homeland Security without border patrol and ICE reforms from President Trump.

And the results has been punishing not just for unpaid TSA agents — but also for travelers forced to endure hours-long waits to get through security checkpoints.

Houston airports have been hit particularly hard, with severe waits mounting almost every weekend since last month.

Bush Intercontinental’s five security terminals were reduced to two on Monday, and the line snaked down three floors into the airport’s subway system.

Things had barely improved by Tuesday, with wait times at Bush eclipsing the four-hour mark.

Most other major US airports had relatively normal wait times by Tuesday, with the Newark and its hour-long wait the outlier.

It remains unclear why Houston’s airport call-out rates are so much higher than the rest of the country.

Neither airport responded to The Post’s request for comment.

The problem has gotten so bad that Trump ordered ICE agents deployed to at least 14 airports to help bolster TSA operations.

Dozens of agents were seen at airports — including Houston, New Orleans, JFK, Atlanta, Newark and Philadelphia — moving thorough the security lines and directing traffic.
