Majulah,
EVERY carrier I have worked with( And ALL were premium national carriers amongst the top four in the world today ),always HAVE and always WILL be hiring expats for basic survival and day to day operations.That is the norm and always will be. Basic numbers will dictate the existence of expats around the world AND in SIA too.If you are a pilot you are either a local or an expat.Anywhere in the world.No other kind la.Please remember I'm an expat in singapore but in my home country,I was doing the hiring OF the expats!
So you would be incorrect in suggesting that other National Carriers don't hire expats.You couldn't be more wrong.They SURVIVE on expats!
Thanks...
