DUBAI, June 3 (Reuters) - Saudi budget airline flyadeal

is studying a possible order for between 10 and 20 wide-body

jets to carry more passengers, and could make a decision by the

end of the year.

The low-cost subsidiary of state carrier Saudia is in the

early stages of comparing the Boeing 787 and Airbus A330neo, CEO

Steven Greenway told Reuters. It has not yet started a formal

competition between planemakers, he added.

Such a deal would be worth up to around $5 billion at list

prices, though airlines typically win sharp discounts.
