In December, the loss-making carrier signed a provisional agreement with Airbus to buy 25 aircraft in a deal worth $4.4 billion (2.6 billion pounds) at list prices.

The order includes 10 A350-900 and 15 medium-haul A320neo airliners.

It was delayed after a parliamentary investigation was launched this month to investigate all contracts signed by state-owned Kuwait Airways.
