It was a quiet morning at Houston’s busiest airport terminal Sunday with wait times at security checkpoints well below an hour, despite staffing shortages and flight cancellations on the 40th day of the government shutdown.

Passengers entered security lines free of any major backlog at George Bush Intercontinental Airport’s Terminal E, where wait times were an estimated 40 minutes, according to the Houston Airport System. The checkpoint lines appeared even shorter shortly after 8 a.m., and they were about 10 minutes at William P. Hobby Airport, airport officials said.

FROM SATURDAY: Wait times at Houston’s IAH and Hobby airports decline as number of canceled flights rises

Sunday marks the 40th day of the government shutdown, which has halted paychecks for Transportation Security Administration employees, air traffic controllers and other federal employees. Some have stopped showing up to work, causing major delays at security checkpoints in Houston, reaching three hours at Bush beginning a week ago.

The FAA on Friday started canceling flights at 40 of the country’s busiest airports, including IAH and Hobby, to reduce pressure on air traffic controllers who have continued working. Those flight cuts started at 6% Friday, will increase to 8% Thursday and hit 10% the following day.

As of about 9 a.m., 39 flights had been canceled at Bush, according to FlightAware. Fourteen were canceled at Hobby.

TSA wait times still have the potential to grow in Houston. Airport officials said they could be as long as 60 to 75 minutes at Bush Airport later Sunday and 30 to 45 minutes at Hobby.

The scene at Bush Airport’s Terminal E was a welcome sight for Karine Hall, who was in Houston for a layover between Utah and Mexico on Sunday morning. Her terminal had switched from D to E because of the reduced number of security checkpoints at the airport, but Hall said the recent airport news hadn’t affected her plans otherwise.

She showed up at the airport “ready for whatever,” but TSA waits didn’t pose much of a threat two hours before her 10 a.m. flight.

“Today is really slow compared to what I was expecting,” she said. “It’s really not that many people.”

Eileen Ramirez dropped off her parents at Terminal E more than four hours before their 12:10 p.m flight to Guanajuato, Mexico. It was her mother’s first time flying, so Ramirez wanted to make sure her parents were extra early in case of any issues, especially after seeing the Bush security lines spill out the doors on social media last weekend.

But she was feeling better once they entered the uncrowded security line.

“I feel a little relieved … that everything is a little more managed here, and everything’s going as smooth as it can be,” she said.
