Air France-KLM's board will meet on July 27 to discuss an order for 100 long-haul aircraft to be split between Airbus and Boeing, La Tribune reported without saying where it got the information.

The airline group is looking for 100 lightweight, fuel-saving aircraft in the mid-sized 250-300 seat range and is comparing the Boeing 787 Dreamliner with the future Airbus A350.

The paper said half the orders would be firm and the rest options, adding that the order would be split between Airbus and Boeing and would be announced in September.

Air France-KLM said earlier this month it hoped to announce the results of the contest during the summer. Officials at the airline have said the order was likely to be split between the two manufacturers.

The order would be worth US$25 billion at list prices, but airlines negotiate discounts when renewing their fleets.

Air France-KLM declined to comment.

The airline, Europe's largest by revenue is 15.7 percent state owned. It has come under pressure from members of the French parliament to order planes from Toulouse-based Airbus, instead of Boeing.
