Europe's biggest low-cost carrier said it was placing a firm 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 deal delivers a boost to the 737 MAX, Boeing's best-selling jet whose deliveries have been depressed by a two-year safety crisis and post-COVID disruption.
"Boeing wanted us to step up the scale and size of the order even to get the discounts that we [got]."
Boeing Chief Executive Dave Calhoun countered during a press conference that no premium was high enough for the jet, in a jovial back-and-forth.
On Monday, Reuters first reported that Ryanair was close to a major deal for Boeing jets.
