On what is expected to be the busiest air travel day of the Thanksgiving holiday period this year, the Federal Aviation Administration warned about a possible ground ground delay at Newark Liberty International Airport.

Due to staffing shortages, the Federal Aviation Administration has implemented a ground delay at Newark Liberty International Airport on Wednesday, one of the busiest travel days of the year.

The FAA is slowing air traffic into Newark Airport as a result of staffing shortages the day before the peak Thanksgiving travel begins, according to the FAA website. The ground delay program at Newark is in effect until 1 a.

Bad weather and not enough FAA employees caused more than 200 delayed flights Tuesday, according to United Airlines officials.

The Federal Aviation Administration is using military airspace specially opened for civilian use to ensure smooth travel during the holiday, officials said.

You’ve done everything by the book — got to the airport hours before departure, followed TSA guidelines about what can’t be put in carry bags, even remembered to wear slip-on shoes to make the getaway to the gate faster.

Airports across the United States are preparing for what is anticipated to be the busiest Thanksgiving travel period ever.
