As a long serving Senior member of the Qatar Airways crew,the only advise I could give you is,Stay away from them as much as posible.
In terms of growth,the company is rising and the truth must be said.
Humanity and human resourses at QR towards staff is concerned-FORGET IT.
If you must fly in the gulf, look for other options in the region such as Etihad, air arabia and Bexair together with EK. because once employed by QR, you are F**ked for life. dont let it happen to yourself.
DOH becoming DXB is concerned,....well, it willhappen some day.question is, when!!?? DOH is so many years behind DXB and DXB was still better 10-15 years ago than DOH today.
Final advise-Read more on this page under middle-east and QR on this site and decide yourself.make the decision correct. Do not regret later.
