I think that, beeing with QR,EY,or EK ? the salary, accomodation ( nice one ) and the rest of the benefits are raghly the same. However, befor thinking to that, you’ll have to aske your self if you are really ready to be a cabin crew, because all what I can tell you is that it’s a very hard job, and at the end of they day, you’ll be so tired that you’ll not care about the greenery of the grasse ( wich is a fake one lol ) but just about a peace of something where you can sleep !
And talking about Expat, you’ll never find locals working as cabin crew. They are too rich for that !
