Yossy,
There are a lot of other factors that must be worked in.
I can't speak for anyone else, but for the past 3 months I have been rostered 90hrs + each month. This duty time begins 1hr before departure, however pre-departure briefing starts 1hr 35mins before departure. Duty ends when the brakes are set, even though you are not generally of the jet for another 20-30mins later.
You will find that a majority of Duties are on the back of the clock, and quite often in some very challenging environments. Classic example. Mumbai turnaround. Get picked up from home at 7:30pm for 9:45pm Dep. Arrive Mumbai around 1am and then 1hr 30 mins on ground. Dep around 2:30am to arrive DXB around 6am. Leave HQ around 7am and home again when ever the traffic allows.
Sounds pretty straight forward, but when you factor in poor ATC, local traffic, badly equipped airport facilities, monsoon, likely holding back in Dubai it becomes a very fatigue ridden duty. Compound the effects by whatever other duty(s) you have had prior, and I think you get my point. I'm not trying to paint a bleak picture, but that is exactly what you can regularly expect with EK.
Bit of food for thought. Happy to stand corrected if anyone has a different view to this kind of pattern.
