Etihad is about to cancel thier A359 order thus opening thier slots imediately as they are due for delivery end of 2019. A380 to A359 course only takes a few days. Also we can buy thier A359 sim thats about ready for delivery as well!
So A359 order seems a good choice. Expect these in our fleet by early 2020.
ref to the A330 NEO, we need 280pax aircraft to operate on lower dencity routes as the loss we currently make on 777ER sectors is not good. Althou no idea when well get A330 NEO slots.
And finaly the 787 order. These will be concerted to 77Xs.
Our A380/777ER fleet numbers will reduce significanly as over next few years they being returned to lossors. Hence we need the A359 to cover this shortfall. Only about 50 A380 will be kept at the end and lease extended till the end of the airframe cycles.
I personaly think its a very wise choise what they doing with this new fleet arangement. Might not make sence to a few to have again 4 fleet types but in the long run it will be better.
