Entirely depends on the route and origin. ex-AUS is generally worse - often the 'Saver' rules apply. Some are fully flex & refundable, obviously a lot harder to know when booking over the phone now. I recall changing most intl ASAs I've booked. Generally can be done online with very little fuss. Occasionally I have rang and added sectors or completely changed the route. Only once did they forced a rebook fee of $60 or something, otherwise it has always been just the fare difference. They do not charge additional points... cash only.

Not my experience last week. I had to change one flight on an upcoming TSV/BNE/AKL/BNE/TSV JASA or else I would have missed a connecting flight back to Sydney. On line it would have cost me around $814 just to change it to an earlier flight from BNE-TSV on the return leg. Over the phone cost me $140 which was $100 change fee and $40 Assistance fee or 3500 points for the assistance fee.
Changing flights online is ridiculous BTW. I just threw up one of my bookings which was just a cheap sale fare SYD/BNE/SIN in Y for the family in April next year which only cost $827 p.p. If I wanted to change a flight online, this is what I get per person:

Am I the only one thinking that is a bit over the top? The four prices (L-R) are for sale, red-e deal, super saver and flexi saver.
