Houston airport has become a symbol for the shutdown's impacts on air travel

"Frustrated travelers at Houston's largest airport have confronted warnings of four-hour wait times to get through security, as many Transportation Security Administration workers aren't showing up for their shifts since they're not getting paid during the shutdown."

"Both Bush Intercontinental and Hobby, the city's other major airport, have had some of the highest callout rates in the U.S. While 11% of TSA workers nationally did not show up for work on Tuesday, at Bush Intercontinental, that number was nearly 40%."

"The callout rate in Houston has averaged between 35% and 40%, said Johnny Jones, the secretary and treasurer for Council 100 of the American Federation of Government Employees, which represents TSA workers nationwide."

George Bush Intercontinental Airport in Houston is experiencing significant delays due to a high callout rate of TSA workers during the government shutdown. Travelers face long security lines, with wait times reaching four hours. The airport's challenges are attributed to economic difficulties faced by TSA workers, increased passenger traffic, and a busy tourism month. Nearly 40% of TSA workers at Bush Intercontinental did not report for duty, contributing to the airport's struggles compared to national averages.
