My tuppence worth .... airlines based in Gulf States have a good safety record as far as I know (and I've lived in the region for years...as SLF). Some from nearby countries less so. I'm thinking of Iran Air, & Yemenia as examples.
Some airports are not so hot though. Abu Dhabi recently may have had issues with runway lighting (thread in PPRuNe). Kuwait has had a fire a few years ago that spread much further than it should have done through the Terminal Building - and no standby generator in service for emergency lighting, etc...
Your safety when travelling is drop-off to airport pickup - not just in the air.
