BECMG is right, the singaporeans never really were fond of silkair, not because of the MI185 incident but probably because they were paying SQ prices and expecting SQ standards.
You'd hear alot of customers who booked fares and went totally berserk because they were thrown onto a silkair operated flight when they booked their tickets on the Singapore Airlines website.
And they have a mentality that if they'd have to book a flight from silkair, they'd rather do it on Jetstar, Airasia or Tigerair because at most it's a 3 hr flight and I'm not paying premium for that.
