Ek still sniffing around the 748, as it is needed for SFO / LAX. You just have to watch the number of 'significant' people who fly to SFO then on to Boeing to know something is up and not just another 777 order. For info though, Boeing rubbing EKs nose in it as EK didn't take up the initial offer (longer range, shorter upper deck) when they were given the chance of a lot of input into the design. Typically EK then started wingeing when Boeing went with the design the other carriers wanted (more seats, shorter range)even though they had not shown any interest. Also EK still has a 748 project pilot (though what qualifications he has to be in the job I have no idea, I believe never flown 747, joined on 310 cargo then as Eds best mate got the transfer to 777!!!!). The FOs love him - NOT!
So anyway 748 still a possibility but tied up with politics of A350 / 787-1000 / engine selections and 777 300LR!!! A long complicated story!
Remember its a rumour network, but this is what I heard!!
