Not a bad option for the short-term
Worst decision? Not at all.
Emirates was, for me, a really interesting blip in my career. If you want to see the world in new aeroplanes and fly for a highly organised institution and be relatively well remunerated, it's a pretty good option. The tricky question is : is it sustainable? Just like many low cost airlines, Emirates will f*ck your life expectancy in return for the experience it offers you.
If you can afford to try Emirates for a few years for the experience, I would highly recommend it. If you join expecting it to be a long-term option, I would encourage you to re-read these threads.
