Yes I am very happy with the cost of my fare and am looking forward to my first time with SWISS. My 13 digit ticket starts with 724 and is the same number for all flights even though i fly HKG to MEL with Cathay and returning fly MEL to SIN with Singapore Airlines before rejoining SWISS. The only thing i haven't been able to do is reserve seats on the non SWISS flights, although i am assured that my wife and i will sit together.
Anyway thank you everyone for all the comments, I didn't think it would create such a discussion. Clearly a few people on here have a lot of knowledge about the subject.
Many thanks..
