Funny i was just visiting the site yesterday, and then today i read youre post...by the time of writing this, all the dates i checked are minimum 202€ OW.
when i tried earlier i actually found some cheap fares on dates i wanted but theyre servers went haywire, and booking failed...
tbh. Air Asia LH is nothing i would gladly do, unless price is "right"...
But if "normal" fare is 202€ OW then id rather throw a few extra € at a legacy carrier.

well the easiest way i browsed theyre prices were with mobile.airasia.com..then press next day repeatedly(Oldschool, but fast)...
