I have some Qantas points and want to use them on Jetstar flights, not Qantas flights, because Jetstar is far cheaper. I cannot find any way to use my Qantas points on the Jetstar website. I found some instructions telling me to go to the Qantas website to buy the Jetstar flight, but the points use is a rip off compared to the Jetstar website price. For example, flying to Singapore, one Jetstar flight is $176 on the Jetstar website, but using points on the Qantas website, the same flight costs 25,000 points plus $136. 25,000 Qantas points should be worth far more than $40. Any way to use Qantas points to buy Jetstar flights without getting ripped off?
