LEPs are more than welcomed to apply to air carriers in the Middle East and receive expat benefits, but I am guessing none will, they want to have their cake and eat it too.
Just like some of us who are based outside Hong Kong, but want a full 13th month's pay plus Expat allowances. We're all the same mate.
Also, The LEPs are bonded for 7 years. Although I have been told it's not enforcible in Hong Kong.
