With a funding deadline approaching, workers are bracing for the possibility of a disruptive holiday season, which could include longer wait times for travelers.

As many Americans begin their holiday festivities, service members are facing uncertainties as a potential government shutdown looms.

With the U.S. on the brink of a government shutdown — right before the holidays — the impact on travel would most likely be minimal.

With one federal spending bill now scrapped and a revised version still up in the air, the U.S. faces a possible government shutdown that could begin at 12:01 a.m. on Saturday, Dec. 21, when current funding is set to lapse.

A shutdown furloughing hundreds of thousands of federal workers would restrict a wide range of government operations, although critical services would continue.

Although Republicans have produced a last-minute bill that would avoid a government shutdown, there’s still a fair chance that lawmakers will fail to agree on the path forward in the next 36 hours, resulting in the loss of some federal functions starting at midnight on Friday.
