OK, my bad! I took the time to go through some old plans & found some tankering sectors - MLE, BEY, ISB. But not AMM for some reason. Sorry, my mind grows dim & I should have checked before shooting my mouth off!
However, I guess the point I was trying to make is that if fuel in DXB was so cheap that it gave EK a significant advantage against other airlines, as some suggest it is, EK would be tankering to MTOW (or MLW less buffer, if limiting) on almost every sector out of DXB. And that is just not the case.
People seem to make assumptions such as - Middle Eastern country - produces oil, so fuel very cheap for locals - EK must get it so cheap that they have an unfair advantage. I believe that most, if not all, on this forum have no idea what EK, or any airline for that matter, actually pays for its fuel anywhere in the world.
