Still learning how to 'use-my-miles', so your opinions are appreciated.

Trip isn't until fall of 2016 for 2 adults - so plenty of time. Great learning opportunity for me! Want to go in suites (where available).

Since I'm not able to book LAX-JNB all in F (or is it R?), due to only J (D?)available SIN-JNB online - I should be able to call SQ customer service and book LAX-SIN (SQ11) + SIN-JNB (SQ478) all for 182,750 Krisflyer saver miles (this includes the online 15% discount).

Just wondering if I have to book two separate awards, since I can't get it to work online.
