Trying to book a first class ticket on LH using miles and have been watching Co.com for 5 months and LH has not opened up first class seats on the A380 yet.

8 seats and only 6 are taken (based on LH.com paid ticket search)

Anyone know if historically LH releases the remaining first class seats for award as I get closer to my travel date?

I am 3 weeks out right now.

Platinum CO (if that even matters).

Thanks
