Saturday delays at Newark Liberty International Airport.

According to Flightaware, there have been at least 302 delays and 80 cancellations today so far. This is the second day United Airlines announces 35 flights cut from Newark every day Due to equipment and staffing issues.

"It's obvious now - the FAA told us - Newark Airport cannot handle the number of aircraft planned to run there in the coming weeks and months," said co-CEO Scott Kirby. "It's disappointing that Newark has reduced its timeline further cuts, but because it's not possible to address the recent structural FAA staffing issues, we feel there is no other option to protect our customers."

According to the Federal Aviation Administration, some arriving flights were delayed by more than three hours. The departure time was delayed by up to 45 minutes.

A FAA spokesman blamed the problem on equipment problems, runway construction and staffing shortages in Philadelphia, where the traffic control center oversees Newark airspace.

Transport Secretary Sean Duffy announced plans to revamp decades of air traffic control systems on Friday, saying details will be revealed this week.

"I came up with a plan that will build a brand new air traffic control system, the most advanced, gilded, jealous world, touching every stage of the system used by air traffic controllers. We are going to lay fibers and we will get new radars, new radios, new ground sensors."

Meanwhile, travelers at Newark Airport were angry.

"As a passenger, it's frustrating when you want a seamless and smooth day," Lisa Tarter said.

"My sister-in-law was said to have been waiting on the tarmac for about three and a half hours yesterday," Michael Harbert said.

Another traveler said: "I'm excited here, but I think I might have a uniform flight on my way back, hoping it won't be cancelled."
