What are the hurdles EK facing from 1) Refitting aux tanks and 2) MTOW upgrade paperwork.
As we have been told EK has world class MX/MRO facilities, and if they want they can design and build B777 and A380 on their own. They are purchasing from other peasants out of charity. So #1 should be easy peasy lemon squeezy.
And we also have been told it is a profitable enterprise and loaded with cash, so Boeing CEO should be delivering the upgrade documents personally.
Unless they used the tanks to transport something very important.
