Ryanair expects Boeing to get certification of its 737 MAX 10 aircraft in the third quarter, with deliveries set for early next year, CEO Michael O'Leary has told Reuters at an event in Brussels.
That is more specific timing than Boeing has provided.
Boeing declined to comment on Michael O'Leary's statement yesterday.
Certifying and beginning deliveries of the largest of its 737 MAX family is critical for Boeing's financial recovery following years of crashes, crises and regulatory problems. The 737-10 competes with European rival Airbus's A321neo, which has been in service since 2017.
Ryanair ordered 150 MAX 10s in 2023, with options for another 150. The airline already operates high-density 737 MAX 8s.
Boeing plans to build 30 737-10s this year for delivery in 2027, Chief Financial Officer Jay Malave said earlier this week at the Bank of America Global Industrials Conference in London.
Malave said the company is on track to certify the two remaining 737 MAX variants - the 737-7 and -10 - in the second half of the year.
"There's a number of aircraft systems and capabilities and functions that will have to be (flight) tested" before the planes are certified by the US Federal Aviation Administration, he said at the event on Tuesday.
Those include the models' autopilot systems and engine anti-icing systems.
Boeing has delivered more than 2,000 of the other two MAX variants - the 737-8 and 737-9, which are in service around the world.
The company plans to increase 737 production rate from 42 jets a month now to 47 a month by mid-year, Malave said.
"The team is actually working on an earlier date than that, but for purposes of conservatism, (it is) around mid-year," he added.
