Monarch Man, I personally know one person who returned from Europe in the Winter (3 hours different from Dubai) 20 hours before a ULR flight, was pulled off the flight and dragged into the office for tea and biccies. I agree with your interpretation of the rules but the company sees it differently. If you have been doing it that way it just means you haven't been caught yet. When and if you are it is unlikely to be pleasant for you.
