Speaking to Reuters on the sidelines of an aviation conference, he said he will also discuss the certification of Boeing's 737 MAX 10 aircraft and ongoing issues with oversight following the Jan. 5 mid-air loss of a panel on a new Alaska Airlines MAX 9.
The meeting will be with the "highest levels of management" at Boeing, he said, without identifying who.
"We are working closely with Boeing. (...) Boeing are still producing great aircraft, but there's no doubt in our mind that on the shop floor, the systems and the quality control in Seattle need to be improved," he said, referring to Boeing's main manufacturing hub in Washington.
He said the budget airline, Boeing's largest European customer, has regular meetings with its plane supplier and believes things will start to improve as regulators ramp up scrutiny of the company.
"They're being (...) heavily regulated at the moment by the Congress, the FAA are crawling all over them. That doesn't help monthly production. But frankly, it's that kind of oversight it needs," he said.
Last month, O'Leary warned the carrier may have to cut its summer schedule, the busiest time of the year, due to delays in receiving new aircraft.
Boeing declined to comment on the meeting.
The U.S. planemaker said on Wednesday it would burn more cash in the first quarter than previously expected as it constrains 737 production to improve quality.
