Dear all,

please consider this situation:
Lufthansa SEN or HON member, based in Germany.
Now flying SQ on a regular basis, all the time FRA-SIN or FRA-NYC in first or business class (about 6-8 returns per year), i.e. total spend of 50k EUR / 75k SGD, +/- 15k SGD, as long as LH does not fly F on this route.

Option 1: Collect all miles to LH program Miles and More. Status miles are not needed, as status is easily achieved anyway. Therefore, the only gain would be award miles.
Option 2: Collect to Krisflyer for SQ flights; easily achieve PPS, maybe even PPS Solitaire.

What option should one go for? What is the value being PPS or Solitaire being based in Germany and only flying premium cabin?

Any insight, personal view etc. would be most appreciated!

Thank you!
