In the hour-long meeting, Trump reportedly asked American CEO Doug Parker why the airline’s stock price had fallen despite a surging market. He also took Delta to task over the fact that CEO Ed Bastian didn't attend the meeting and because it purchased planes from Airbus instead of Boeing, according to NBC.

Trump noted that Qatar Airways purchased jets from Boeing, according to NBC.

In addition to the CEOs of United and American, the meeting was attended by acting White House chief of staff Mick Mulvaney Mick MulvaneyOn The Money: House panel pulls Powell into partisan battles | New York considers hiking taxes on the rich | Treasury: Trump's payroll tax deferral won't hurt Social Security Blockchain trade group names Mick Mulvaney to board Mick Mulvaney to start hedge fund MORE, Sen.

“The president kept going back to it,” one person who attended the meeting told NBC News. “There was a lot of yelling.”

Trump also reportedly took a dig at Qatar Airways CEO Akbar Al Baker after he called the American and United CEOs “liars,” telling Al Baker he takes money from the Qatari government.

The “Big Three” carriers have argued Qatar Airways and United Arab Emirates-based airlines are undercutting them, aided by government subsidies. In particular, they have argued that Air Italy’s addition of new flights between Milan and the U.S. after Qatar Airways bought a stake is an end-run around the U.S.-Qatar “Open Skies” agreement.

The Partnership for Open and Fair Skies, which represents the airlines, said the meeting had been “productive,” while United CEO Oscar Munoz said the airline looked forward to “continuing to work with the administration,” according to NBC News.

The White House did not immediately respond to a request for comment from The Hill.
