I wasn't aware of this issue. Here's the scenario.

SIN-MEL-SIN - If you book Flex on the outbound and Saver on the return, Skywards treats the whole itinerary as a SAVER in terms of miles required to upgrade any leg.

So, technically if I want to upgrade the SIN-MEL sector and that leg is priced and ticketed as a FLEX fare, I need to burn 37,500 miles (Saver rate) - rather than the Flex rate of 30,000 miles.

Doesn't seem logical or fair if you ask me.

I think this issue is going to start to raise its head now after the raft of changes to the booking engine where Saver fares have become far more prevalent. The system will now often book a combination Flex/Saver itinerary.

I wasn't aware of this.

Anyone else experience this?
