I also made my first two Plats with CX and AA. Now I'm not sure if I revalidate my platsku or should I stay in gold. Of course I need this platsku thing but everyday life is getting more and more disturbing my hobby.
Btw, good way to earn points is J rt ticket DEL-YYZ for btw 1800 - 1900 €. If you are already Plat and add for example value STO-DEL rt here you can earn over 100k pts in one trip easily under 2500€
