Travelers moved swiftly through security screenings Thursday at the Baltimore-Washington International Thurgood Marshall Airport. It’s a stark difference from the massive lines at the airport last week, when some travelers waited more than four hours to reach security checkpoints.

A surge of spring break travelers collided last week with Transportation Security Administration workers not being paid during the partial government shutdown. Thousands of TSA workers called out at BWI and airports across the U.S.

With more than 27,000 people expected to fly out of BWI Thursday, here’s what you need to know if you’re headed to the airport.

What’s the wait time? Operations appeared mostly normal around 8 a.m., but digital boards continued to display messages saying “checkpoints are experiencing longer than normal wait times.”

Travelers are reporting wait times of less than 10 minutes on social media, though lines to check bags with some airlines were long.

Airport officials recommend people arrive two hours ahead of their flight.

Which checkpoints are open? Checkpoints A, B, C and D/E are open, including most lines for TSA PreCheck and Clear.

Passengers waited in longer lines inside the terminal at Jamba Juice and Chick-fil-A than at security checkpoints.

Travel mess at BWI

More than 30,000 travelers were expected to fly from BWI last Friday and Saturday for spring break, which began last week in several school districts in Central Maryland.

Several security checkpoints at BWI were closed due to TSA staffing issues last week, and wait times stretched to nearly four hours on some days.

Over 38% of TSA workers at BWI called out on Sunday, the highest rate in the U.S., according to figures provided by the Department of Homeland Security. After President Donald Trump signed an executive order to pay TSA workers, callout rates dropped significantly at BWI to 10.5% on Tuesday.

Baltimore County’s spring break started with a short day on Wednesday. More than 27,500 passengers are expected to fly from BWI on Thursday, said Jonathan Dean, a spokesperson for the airport.

Last week, Trump deployed federal immigration agents to help airports facing travel disruptions. On Thursday, federal immigration agents, dressed in vests labeled ICE or ERO, maintained a visible presence at security checkpoints but appeared to have little to do.

One stood with his arms folded by the screening belt. Another stacked empty bins onto a rolling cart, then stood to the side and glanced at his phone.
