Miles & More (Lufthansa, Austrian, Swiss, and other partners) - what routes=best odds for NEW F or New C from Europe to US

Hi,

what destinations is most likely to have new F or new C from Germany to USA?

I´m about to book 2 award flight in F (or C if I cant get F) september 10-12 and my final destination is Las Vegas but I am willing to make an extra stop just to get new F or C. Since its pretty hard to get an award flight on 380 and 748, I need to take my chances... My return will be on 17-18/9.

So my questions is what routes that has the best possibilities of:

1: NEW F (all metal)
2: New C (ex 748)

Thanks guys

I'd be interested as well in both the 748 and the 3's as I'm planning a trip to Detroit end of October.. anybody point us to a LH source maybe ?
