ALAFCO has ordered 12 A 350s so it would be no surprise if KU
being a Kuwaiti company too got hold of a few of them.
But the A 350 is too big of an A 310-300 replacement but an ok AB6 replacement.
However if you posess the new JUSTPLANES dvd on Kuwait Airways, on disc 2 there is a long interview with the current KAC chairman and you can clearly see on that interview a huge Boeing 787-800 model on display
With USA helping out Kuwait so much with regards to the Iraq war, I would expect the current Bush Administration to play a key role in this order.
KUs AB6s and A 310-300s need to be replaced soon and neither the A 350 nor B 787 can delivered before 2012 to them therefore a perfect interim solution would be placing an order for A 332s which can be delivered by late 2007/early 2008 as this aircraft is a perfect replacement for both its A 310s and A 300-600Rs.
For the future, the newly proposed B 787-100X is a perfect replacement for its A 343s and B 772IGWs.
