Maghy,
I have no inside info. We have been told that DXB capacity is limiting EK expansion to 260/280 aircraft (cant remember which it is) until it moves to the new aiport in 2025. EK has 176 aircraft now. So lets call it fleet growth on 100 airframes in the next 13 years.
We now have 107 of the 160 Boeings we have been told will be in the fleet.
Going by the orders now the Boeing fleet will grow by just under 50% and the Bus fleet by a bit over 90% in the next 13 years.
I think its 65 DECs that are being hied this year.
Plan on a longer time for a command, and be pleasantly surprised if it happens earlier.
