exist More than 500 flights were affected on Sunday.

As of 8:30 a.m. Monday, the airport reported 20 delays and 73 cancellations, and those numbers are expected to climb over the day.

New Jersey Gov. Phil Murphy said on social media over the weekend that the issues were "completely unacceptable".

Some are beginning to wonder if the airport will be able to handle a large number of flights in the coming summer.

"The FAA is really a mess," Schumer said.

"To say that Newark Airport is just trivial turmoil, and the FAA will be a year of understatement. We're here because the FAA is really a mess. This chaos requires a real forensic look, a deep look," said Senator Chuck Schumer. "So today I'm asking for a full inspection of what's going on."

Schumer said he hopes the investigation covers Newark and the entire East Coast.

"If such a problem is not resolved, the chaos in Newark is likely to be a harbinger if the FAA cannot set the real solution apart," Schumer added.

Schumer noted that the national shortage of air traffic controllers on the FAA due to government efficiency departments, old technologies such as copper wires that are still in use, and exhausted federal funds.

"So, this is a bigger warning we need to pay attention to," Schumer said. "Air traffic controllers have long warned the FAA that there are problems here, but the FAA waits. There are chaos, there are cuts. That's why the Office of the Inspector General of the Department of Transport must immediately tidy up the FAA's administrative, operational and capital functions."

Schumer said there were several questions to be answered, including one about the recent bonuses offered to other air traffic controllers to stay at work.

"Because they know the shortage, they offered $10,000 in bonuses to 13 different air traffic control towers, but not to Washington, Philadelphia or New York. Why? Why? Since we are the people who need it the most, it doesn't make sense. These are places where the shortages are causing real problems."

Schumer also said the recent Doge cuts should also be checked recently. Old equipment such as copper wire and floppy disks also need to be reviewed, and key leadership vacancies need to be filled in.

"If the severe shortage of air traffic controllers continues without a solution, airport Newark Liberty will continue to cope with very significant operational disruptions," Schumer said.

Delay and cancel stacking

On Monday, Newark's flight board told the story: delays and cancellations piled up for three hours.

Travelers are frustrated with no quick fix. Some people find themselves in trouble.

"We just had a third delay. But it hasn't been cancelled, so we're happy about it," said traveler Sue Tobias.

She is trying to return to Minneapolis.

"So far, it has not been cancelled, but, like I said, we have had three delays so far. But we have no intention of taking off in a few hours."

"We came here for the wedding. On Thursday, we were postponed two to three times, and then we had to change airports and fly to Atlantic City," said Jay Lampiasi, a Florida resident. "(Atlantic City) is easy. It's much easier."
