Just managed to change our MLE-AUH-MEL-BNE flying in J/F/J to MLE-AUH-BNE in J/F. The AUH-BNE leg wasn't open for F redemptions when I ticketed these back in May and just happened to take a look today after reading this thread and it was available. Very easy conversation with EXP AAngel - she saw the flight and was able to make the change and request seats for us. Even save a whopping $0.80 on the taxes! :-) Really wanted to fly on the A380 to SYD but figured that the First Studio on the B789 isn't too shabby.
