HOUSTON (CW39) — Travelers are still facing long lines at Houston’s airports as TSA staffing shortages continue amid the ongoing government shutdown. Both George Bush Intercontinental Airport and William P. Hobby Airport reported heavy wait times at security checkpoints Monday, with some passengers waiting up to three hours earlier this week. Lines eased somewhat later in the day, but travel experts warn delays could return if staffing issues persist. Passengers are being urged to arrive early and plan for extra screening time.
