Rex, I think you misinterpreted me. I didn't sat that EK were unhappy with the aircraft and that they weren't making money with them, it's just the engines that they aren't happy with. It's been public for a while now that EK asked Airbus to develop a NEO version to reduce the fuel burn and after signing with RR for the next tranche, they asked if it was possible to retrofit the existing fleet (not feasible).
EK have an advantage with the price of fuel in DXB that helps make the A380 operations profitable but other A380 operators are finding it more difficult, especially on longer sectors.
