Please be specific what's your route (e.g. ex-HKG to PEK only offers J, so don't dream about that) and Y class loading (could be Y0 B0... already and it's already overbooked, thus CDI all 0)

Of course if it's the latter case KA may suddenly swap in a 321 to offer more J seats but even under such situation unlikely they will release CDI class out
