By the way, I also know some locals who would rather fly SQ than QF from CGK to Australia although that is not the most convenient route.
Ha true, although that may be for other reasons not related to safety. Much like I avoid SQ out of SIN if I have other options such as QF, TG or CX, SQ really has their tongue in their cheek when they refer to KrisFlyer as a "Loyalty" program.
