You cannot come to Dubai thinking you can commute. All it will do is lead to frustration, and strain on the family. If you don't think it is right for your family, best to stay where you are. As payscale says, rules change here regularly. The latest is a 'fatigue module' input in roster builds, which has essentially eliminated any chance of more than about 4 days off in a row. It is also difficult to get days off around leave now due to crew shortage. However, why not come down and do the interview, have a look around, and then decide. EK must realize that they need you now, probably more than you need them. When you see it first hand, maybe it might just suit your family?
