Just got my statement and I got 780 points and same status points for the Langkawi trip which is points on the entire $345 of the booking. I did only get credit for 2 nights and had to write about the other 2. So perhaps it got submitted a bit funny.

Interestingly, I ended up paying another 2000 points to round up the bill so this total stay cost me about $5USD which is under the $10 threshold mentioned earlier.

Net there's a lot of YMMV out there with systems etc.
