Please. Read the fine print if you get any, you need to know what you are signing up for.
Prepare to be treated like a moron. The company will try to work you as hard as they can. If you object because it is illegal, then expect warning or dimisal. (or standby for an month). Have a backup plan.
The routes are average at best, If you like variety between the third world and 2nd. Then this is the job for you.
The aircraft are old, the passengers expect the best, but you are provided the worst to provide to them. Working entertainment systems are completely optional to Gulf Air, as a World Class Airline.
Just do your homework. There is a high turnover of cabin crew in Gulf Air for a reason.
