I assume you are a Captain. If not then avoid joining any expat Airline as an F/O as Upgrades are not always available.
If you have years of service behind you in the UK IT Airline business and you are financially secure then I guess you just fancy a change to flogging up and down to the Canaries and Greek Islands night after night?? In which case night flights to Dhaka,Karachi ,Lahore, Jeddah etc etc will make you feel at home!!
If you have children of School age then you need to look into matters very carefully. Others who know AUH may be able to help.
Personally I would not give up a half decent job to join Gulf Traveller. OK for those unemployed or on furlough.
