UPDATE 1-Boeing snares Hawaiian Airlines widebody jet order from Airbus

(Adds background on competition, details on order)

NEW YORK, March 6 (Reuters) - U.S. planemaker Boeing Co has snared a Hawaiian Airlines order for widebody long-haul jets from European rival Airbus, the carrier announced on Tuesday, in a striking blow to Airbus amid dwindling widebody sales.

Hawaiian said it had placed an order for 10 Boeing 787-9 aircraft, with the first expected to arrive in 2021. The carrier dropped an earlier order of Airbus A330neos to go with the Boeing series.

"We ran a competitive process between two great aircraft types. It was a complex decision that factored in many aspects of aircraft capability, passenger experience, fleet complexity and the total lifetime cost of ownership, and the 787 came out on top," Hawaiian spokesman Alex Da Silva said.

Pressure has been mounting on the Boeing and Airbus to capture and maintain customers in the fiercely competitive industry. (Reporting by Alana Wise Editing by Tom Brown)
