PARIS, March 27 (Reuters) - The head of European budget

giant Ryanair praised relations with Boeing ( BA ) under

its new leadership and said the planemaker had agreed to supply

alternative jets in time for summer 2027 if it fails to certify

its new 737 MAX 10 this year.

"I think we'll get our first 15 MAX 10s in 2027 but Boeing ( BA )

have now agreed, if they don't get certification this year and

they can't deliver us MAX 10s, they will deliver us additional

MAX 8s in time for summer 2027," Ryanair CEO Michael O'Leary

told Reuters.
