Ya, I'm tired too, but I still like the job.
One problem that I have seen is that, although you are limited to two ULR's a month, you might be in Japan one day, back through DXB for a couple of nights then off to SFO.
Even worse, you might end up back to back at the end of one month and then do it all over at the beginning of the next.
If we could stay to "one side" of Dubai that might be better.
I don't think planning takes this into account.
