WASHINGTON/NEW YORK (Reuters) - U.S. President Donald Trump called the U.S. air traffic control system out of date on Thursday and criticized its $10 billion yearly price tag but stopped short of calling for privatization of the program.

“I hear we’re spending billions and billions of dollars, it’s a system that’s totally out of whack,” Trump said during a picture-taking session at the White House ahead of his sitdown with airline and airport executives.

His comments heartened advocates of privatization who have long sought to move away from the system they see as outdated.

“We want to get the government out of the role of managing the air traffic control system,” Gary Kelly, Southwest Airlines Co’s chief executive officer, told Trump during the picture-taking session.

The Federal Aviation Administration spends nearly $10 billion a year on air traffic control funded largely through passenger user fees, and has about 28,000 air traffic control personnel.

Trump said he had been informed that ongoing modernization efforts to the air traffic control system were already obsolete by the pilot of his private jet.

“I hear the government contracted for a system that’s the wrong system,” Trump said. “It’s way over budget, it’s way behind schedule and when it’s complete it’s not going to be a good system.”

The FAA has spent nearly $3 billion since 2007 to implement an updated system, “NextGen,” which would utilize satellites to monitor aircraft instead of radar and make other changes.

“NextGen is one of the most ambitious infrastructure and modernization projects in U.S. history,” the agency said in a statement. “The FAA invited airline stakeholders to help develop the blueprint for NextGen and they continue to have a seat at the table in setting NextGen priorities and investments through the NextGen Advisory Committee.”

The Government Accountability Office said in a 2016 report that the United States “is generally considered to have the busiest, most complex and safest ATC system in the world.”

The chief executives of United Airlines Inc, Delta Air Lines Inc, Southwest and JetBlue Airways Corp were among those who attended the meeting.

After the meeting, Airports Council International-North America President and CEO Kevin Burke told reporters on a conference call that airport officials had urged Trump to lift the cap on airport passenger fees to address airport infrastructure needs.

Trump proposed during his campaign to spend $1 trillion over a decade to upgrade the country’s infrastructure.

FOREIGN CARRIERS

Trump also told the executives he recognized that U.S. airlines were facing pressure from foreign carriers.

Heads of the three largest U.S. passenger carriers - American Airlines Group Inc, United and Delta - have urged the Trump administration to denounce the U.S. Open Skies agreements with the three major Middle Eastern carriers, which they accuse of having been unfairly subsidized by their governments. The three airlines, Qatar, Etihad and Emirates [EMIRA.UL], have denied that their governments unfairly subsidize them. The Gulf airlines operate around 200 flights per week to 12 U.S. cities.

“I know you’re under pressure from a lot of foreign elements and foreign carriers,” Trump said, adding that he wants foreign carriers also to do well.

“They come with big investments, in many cases those investments come from their governments, but they are still big investments,” he said.
