Fewer flights mean shorter lines at George Bush Intercontinental on Wednesday, but TSA waits could hit 45 minutes at IAH and 20 at Hobby.

In an advisory issued on Nov. 2, Houston Airports warned travelers to expect extended TSA wait times “until further notice.”

After hours-long wait times at Houston airports yesterday, here's what we noticed today and what the airport expects tomorrow.

Travelers at IAH and Hobby Airport should expect long security lines due to TSA staffing shortages. Arriving early and being prepared can help you breeze through security and stay on schedule.

Those traveling through one of Texas's biggest airports, Houston George Bush Intercontinental Airport, face long lines for airport security. Due to the federal government shutdown, this has impacted Transportation Security Administration (TSA) staffing across the country. This has led to lines up to three hours long snaking outside the terminal.

Wait times at Bush Airport's Terminal A and E were expected to exceed 60 to 75 minutes on Thursday, according to Houston Airport System officials.
