"It's not rocket science."

Houston travelers facing long TSA lines during the shutdown can check wait times through airport websites, apps and tracking sites.

Increasingly agitated travelers are sacrificing countless hours and missing milestone events as a partial government shutdown spills into its 40th day and the country loses hundreds of airport security employees.

ICE agents, who were deployed to Bush Intercontinental Airport earlier this week, began checking IDs and assisting TSA officers with logistics before Trump made his Thursday night announcement.

IAH posted three- to four-hour TSA waits again Wednesday morning.

"This is the first time I've experienced something like this in my entire life," one traveler said as TSA lines snaked through George Bush Intercontinental Airport.

TSA workers in Dallas have gone unpaid because of the partial government shutdown, but are still showing up to work. Some are even volunteering at the airports in Houston to help with the long TSA wait times there.

As long lines continued Wednesday morning at Bush airport, Houston travelers tried finding ways to make the wait easier and catch their flights.
