Last year I flew SYD-ICN on a JQ Business Max fare and it credited at the Business rate, which earns 125 status credits + 8,450 points. If you book this now on the Jetstar website, it says you'll earn 7,800 points which corresponds to the "Discount Business" rate in the Qantas and Jetstar earning tables.
