Depends on the winds, flight level and payload of course doesn't it. I've done Dubai to UK three times, in 604, during the winter, and routing around Syria. We departed with full fuel (or as near as you can get it with a Chally) and IIRC we still had nearly 1500kg at shutdown, which would obviously cover any diversion etc. But yes, if you have a "full house" of pax and bags then you'll need a stop on the way.
