I am 777 rated and currently flying the airplane. I got shortlisted and got invited for an interview.
But, I was very disappointed to learn that, eventhough, they want you to bring your wife they do not provide any tickets.
So, I am declining the invitation. There is no way you can live in Dubai without having your family approval of the place.
Thank you EK, maybe in the future if you are really interested in having people living in the Emirates you will be kind enough to give a ticket at least to the spouse
