I can't seem to find the answer to this anywhere (sorry if it's been addressed already). I also posted this question in the TK forum.

I'll be flying TK a number of times in the next couple of years. Can I credit the TK miles to my Singapore Krisflyer account? Can this be done when booking online?

I've only flown TK a couple times several years ago and don't recall ever seeing where you can add a different membership # other than Miles&Smiles.
