I can see a third flight from EK happening as opposed to QR or EY launching in the future.
Agreed. In my opinion a third EK service is preferable. A second carrier could result in a price war which could (as in the example of the BHX-Toronto debacle 25 or so years ago) see the airport go from one to no credible service to the Middle and Far East.
Of course the flipside is that over reliance on one major carrier to the region can end in tears (such as was the case with BHX and British Airways).
