In a statement Monday, Airbus says Afriqiyah Airways is also converting its previous order for six A350-800s into orders for the larger A350-900.
At list prices, the four additional jets are worth 1.1 billion euro ($1.4 billion).
The new order comes as French foreign minister Laurent Fabius is in Libya, where he is meeting with President Mohamed Megarief and Prime Minister-elect Ali Zeidan.
