What im suprised at is that Emirates havent launched a DXB-DUB service! Etihad are making a killing on their AUH-DUB route which now operates 2x daily
Firstly, EY at DUB is 10 weekly, and EK dont serve DUB yet as the market is quite finate and there are more competative markets for EK.
Yes, there are connections but EY are mopping up what is currently there. With such a huge fleet, if EK wanted to serve DUB, im pretty sure they would be.
If EK came to DUB, it would probably push EY out so I guess its a matter of be careful what you wish for, and how do you want to succeed
