Hi Doc,
Qatar Awys probably the lowest paid of the bunch, unless they have significantly improved the package.
GF - was not aware they were recruting, but depends if you mean GAMCO in Abu Dhabi (base) or Line maintenance in Bahrain. I wud think BAH the better deal as GAMCO have been trying it on with local deals, no housing allowance, no ticket money etc.
EK- package is more like 45-50k pa free house and tax free but Dxb is a cosmopolitan lifestyle. much more appealing than DOH or BAH
