Air France-KLM has hinted at plans to embark on a huge expansion of its long-haul fleet and is poised to place an order for 100 aircraft split between Airbus and Boeing.

The Franco-Dutch giant is placing the order to the purchase a hundred carriers to replace aging Airbus A340s and McDonnell Douglas MD-11s.

The value is expected to be worth tens of billions of dollars for 100 aircraft to replace older models.

Details are expected to be unveiled next month as the Franco-Dutch airline comes under pressure to support the Airbus A350, the European manufacturer’s answer to the Boeing 787 Dreamliner twinjet.

The French state holds a 15.7 percent stake in Air France-KLM. “The final result will undoubtedly be a balanced result between the two constructors,” a source told news agency AFP.
