Thanks for the input so far - I checked out a few of them and LH does look excellent.
I guess the other concern is making sure that I don't get codeshare metal when doing this (if I am doing it for the experience). I just checked to see about availability for Asiana from NYC and only found 2 options, both flying on Air Canada and Air China metal (using Expedia as that seems to be their booking site?).
If I go for the LH 2 weeks out are these going to open up as Saver awards?
