This is good news for those who don’t have enough miles for a business class redemption but would like a little more comfort than economy. But in most cases from Australia. the difference between economy & premium economy vs premium economy and business are enough that I still suggest you go for business class awards if you have/can get the miles. SQ miles are relatively easy to get with American Express Membership Rewards and several other Aussie bank issued cards transferable to SQ. Remember, you get a 15% discount for awards on Singapore Airlines & Silk Air booked online!
The updated Singapore Airlines award charts – Australia is split between zone 8 & 9.
