EK...DXB to SFO is around 17 hours flight time. I'm sure this must be one of the longest long haul around. 48 hours ( chock to chock ) on the ground in SFO and then it's back to DXB. 2 local nights off in Dxb, and then it's time to go again. 93 hours flight time a month. That's is punishing.
Until I stopped flying, I did not realise just how tired I really was, and what it was doing to my body.
