I say again....
.... stay away!!! EK will kill you health.
I have read something about that you will see the world, hahahaha. Flying 14 hours from DXB to IAH, departing 3 am in the morning, then 24 hrs rest on the paper which does not include passing immigration and transport to the hotel and a pickup about 2,5 hrs before departure time. You might be lucky to get proper rest for your return flight.
Flying to China: 2 men over Himalaya, departures early in the morning, 8+ hrs through the night back to Dubai.
You will see the world, yes, in ****ty hotels close to the airport or far away from the city center, except JFK.
First of all pass the assessment and then you can think about joining. Sign a 5 year bond, another 2 year bond for your upgrade. Upgrade 7+ years, which is still reasonable for a big carrier.
Have seen it, luckily left early enough and enjoy my normal life back in Europe!!!
