As usual, my favourite tool for Star Alliance award research is Award Nexus – I’ll be digging around tomorrow morning to see if I can score me a business class adventure into Asia.
You may also want to check out the reward program conversion calculator to calculate how many points you’ll need to transfer over to Krisflyer from your card program of choice.
Offer expires 9th October, for travel from 1st October to 30th November.
UPDATE: I can’t any availability for either SYD-SIN or SIN-SYD for business class redemption during the promotional period on the flight numbers allowed. There’s availability on other flights, but only at the non-discounted level. Disappointing, but there we go. I’ve checked ~75% of days during October & November, and only in Business – so your experience could be different.
