Yes a captains salary in FZ is the same as and first officers salary in Etihad or Emirates such is the cost of living in the Middle East. I would consider all other carriers in both seats even if you have to swap to the right seat which so many have done in flydubai. This will have huge implications when you come to leave/retire as your end of service benefits is based on your basic salary. Basic salary looks to be a reduced package to the current one.So you will be doing the same work as your co works for a lot less money.
