PARIS, Nov 20 (Reuters) - European planemaker Airbus has won an order worth roughly $14 billion at list prices from Delta Air Lines for 50 long-haul, wide-bodied jets, two people familiar with the matter said.

The order, to be split between the all-new A350-900 and a recently announced revamp of the current-generation A330, follows a closely fought competition with Boeing.

Airbus emerged as the front-runner after it became clear its revamped A330neo could be delivered earlier than Boeing's temporarily sold-out 787 Dreamliner, one of the people said.

Airbus and Delta declined to comment.
