DUBLIN, Ireland: Following an 18-month public feud about jet prices, Ireland’s Ryanair and Boeing agreed to a multibillion-dollar deal for the purchase of as many as 300 Boeing jetliners.

Ireland’s Ryanair, Europe’s largest low-cost carrier, confirmed an order for 150 of the largest version of Boeing’s narrow-body jet family, known as the 737 MAX 10, with options for another 150.

The larger-than-expected agreement marks a long-awaited truce between one of the closest partnerships in the aviation sector, after Ryanair CEO Michael O’Leary broke off talks with Boeing in 2022 over pricing and delays in the delivery of ordered jets.

“I have been told to say there was a competitive discount, although I did not think it was particularly competitive,” O’Leary told reporters as the two companies patched up their differences during a relaxed press conference.

The Ryanair order rose by some 100 planes to help bring the two sides together, he added.

In response, Boeing Chief Executive Dave Calhoun said no premium was high enough for the jet.

Despite price concessions, the new jets will enable Ryanair to almost double its annual traffic to 300 million passengers by March 2034, compared with 168 million through end-March this year.

With more than 600 planes in its fleet or on order, Ryanair exclusively uses Boeing 737s for its mainline fleet and is one of Boeing’s major customers.

The Irish airline has long expressed interest in the 230-seat MAX 10, which is competing with the Airbus A321neo used by Ryanair’s rivals, including Wizz Air.

According to Ryanair, the deal was worth $40 billion at list prices, but this included options, which are not booked as orders, and typical discounts for firm orders run at more than 50 percent.

Newly ordered MAX 10s are scheduled to be delivered from 2027 to 2033.
