DUBLIN (Reuters) -Ryanair has decided not to switch MAX 10 aircraft due for delivery in early 2027 to the smaller MAX 8 aircraft following reassurances from Boeing ( BA ) that they will arrive on time, Chief Executive Michael O'Leary said on Monday.

Boeing ( BA ) promised to tell Ryanair by the end of June whether the new aircraft would be ready, "or we would change back and take more additional (MAX) 8-200s," O'Leary told analysts following the publication of results for the April-June quarter.

Boeing Commercial Airplanes CEO Stephanie Pope has "helpfully confirmed ... in writing" that the aircraft will arrive on time, O'Leary said.
