how much of your flying is during the day? In willing to bet most if not ALL.
99% of layovers at EK will cause your body clock confusion. Ultra Long Haul flying? Night turn arounds to India? time zone changes? It's a different beast. Be careful what you wish for. You'll be right where most of us are one day. We do long haul flying with short haul style rosters and it's not sustainable.
