The statement was that Dubai does not have O&D traffic. That is just a false statement. It has nothing to do with whether or not if it is a wise decision to vacation or work there. Probably close to 70% of the people living in Dubai are expats. That is a lot of O&D traffic in its self.
I know many that love raising their families in Dubai, even some Americans and Canadians. It is not everybody's cup of tea.
