Newark Liberty International Airport faced more ground stops Monday afternoon. The Federal Aviation Administration briefly issued a ground stop around 2 p.m. that was quickly lifted. Another was issued around 4:30 p.m.

As of 9:55 p.m., Newark was reporting up to 75-minute delays on arriving flights.

The ground stops came as New York City's three major airports reported dozens of delays for the Labor Day travel rush.

As of 4:50 p.m., Newark reported 153 flights had been delayed and two had been canceled. John F. Kennedy International Airport had 104 delays, and LaGuardia Airport had 98.

The FAA said the latest ground stops at Newark were due to staffing issues. 

Last week, another ground stop was ordered at the airport, leading to hours of delays heading into the holiday weekend. The FAA said Thursday equipment issues had impacted radio frequencies for some air traffic controllers. 

Tough summer for travel at Newark Airport

The airport has been plagued by problems since the start of the summer. Hundreds of flights have had to be canceled or delayed, partly due to runway construction and partly due to equipment issues that caused air traffic controllers to briefly lose communication on multiple occasions. 

The FAA began limiting flights at Newark and suggested earlier this month that the slowdown should remain in effect until October 2026.

The impacted runway has since reopened, and Transportation Secretary Sean Duffy has said he is working to improve equipment and train more air traffic controllers.
