Actually I am wondering about this for other partners e.g.:
- MH short discount economy segments e.g. KUL-PEN/JHB/SIN
- JL short domestic discount economy segments: e.g. HND-KUH/MMB
- AY short discount economy segments e.g. HEL-BER/RVN
​​​​- SQ short discount economy segments e.g. SIN-BKK/DPS

I remember some of these some of the lowest RBDs did not even qualify to earn any miles previously.
