Sure you could demand a landing against the flow. but my guess is you'd be in the Hold For quite some time before they found an openin for you. These conditions are standard for DXB with it being a coastal airport in extreme temps. There's often a different wind at the touchdown point to the midpoint; so what do you do? There was nothing here today that was even mildly abnormal for Dubai. I suspect there will be something else that comes out of it eventually. The 10kt tail at touchdown will be negligible for EMirates pilots.
