The federal government has now been partially shut down for five days, though many Americans may not yet have felt the effects. If the standoff continues, however, travelers could soon encounter problems at airports across the country.

The shutdown, which took effect early Saturday morning, is limited to the Department of Homeland Security. As a result, air traffic controllers — who work under the Federal Aviation Administration — continue to receive their pay.

Transportation Security Administration employees, by contrast, are generally required to report to work despite not receiving pay during the shutdown.

History suggests that travel complications tend to surface gradually rather than immediately during funding lapses. Roughly a month into last year’s lengthy shutdown, TSA shut down two screening checkpoints at Philadelphia International Airport. On that same day, federal officials took the rare step of instructing commercial airlines nationwide to scale back their domestic flight schedules.

This time, however, disruptions may arise more quickly, according to John Rose, chief risk officer at global travel management firm Altour.

“It’s still fresh in their minds and potentially their pocketbooks,” Rose said, referring to last year’s shutdown experience.

Strains could intensify once TSA workers miss their first paycheck while still facing regular monthly expenses. Some may feel compelled to call in sick or seek temporary work elsewhere to cover essential costs.

“If you have kids, a mortgage, a car payment, food bills—you can’t miss a check,” Joe Shuker, regional vice president of the union representing TSA workers, said during the late 2025 shutdown. “Our members are worried about how to pay for childcare, wondering if they could be saving money by staying home with their kids.”

Although air traffic controllers remain on the payroll, flight operations could still be affected indirectly. Airlines might hold planes at the gate if passengers are delayed at security checkpoints. Staffing shortages among TSA agents could also slow the inspection of checked luggage behind the scenes, adding to delays.

Negotiations between the White House and congressional Democrats remain stalled. According to an administration official who spoke anonymously to the Associated Press, the two sides are “still pretty far apart” on an agreement that would impose certain limits on federal immigration enforcement agents.

Democratic leaders presented a revised proposal to the White House late Monday, but with lawmakers currently outside Washington, expectations for a breakthrough this week are low.

The administration official said the White House remains open to serious discussions aimed at reopening the Department of Homeland Security, which oversees agencies including the Federal Emergency Management Agency and the TSA. At the same time, the president has made clear that any compromise must safeguard law enforcement personnel.

All other federal agencies outside DHS remain funded through September 30.
