With the number of daily SIA services on the SIN-BNE route using B777, A330 and A350 aircraft there would have to be zero demand for EJet travel on that route especially with a pit stop in KTA. There might be some demand for seats BNE-KTA but even in the boom days QF only operated one B737 return service a week. So as rep says in post #2 KTA-SIN has to be the basis of this new service but unless a fixed contract is involved most punters would probably travel KTA-PER-SIN.
