12 years ago it was a no-brainer and the best outfit (by far) in the ME was EK and I would never ever have joined QR.
Now 12 years later it has completely reversed. The best outfit for flightdeck crew in the ME is QR. I hear they treat their FD with respect and rosters are not too bad (if you can get a heavy/super seat). Pay must be pretty similar.
Now if I was looking at the ME and at the start of my career, I would never ever join EK unless I would get a RHS 380.
On that fleet life is still cool because guys get minimum 15 days off a month and so much time to recover. Easy sectors and hardly any night turns or layovers in SE Asia. Upgrading on the 380 will be long away however... From the rumor mill there will be no seats available on that fleet for the foreseeable future (never mind what they tell you during the roadshows, plain lies as many have found out). As we speak guys are transferred (or downgraded) to the 777.
So go a week to Doha and see how life is. Speak with as many people as you can.
Living in the middle east is not for everyone.
