This post has raised some interesting points I have to say.
If the people have the right requirements then why not? EK do employ loads of AUS/NZ/UK/YANKS etc but have local guys to, quite a few for the Armed Forces.
Basically anyone who meets the standard and passes selection has the right to work for them.
I would agree with the above, EK is the national carrier of the UAE so obviously they should employ some nationals.
Would look a bit strange if BA the flagship of the UK only employed French pilots!
