Thank you guys.
Last night I was able to be put in the wait list by the really nice agent on the phone to LH Senator Germany about 6am. I asked her about my chance, and she said looked pretty good, and she would like to make sure her supervisor would clear that for me.
After 9am I checked my "Checkmytrip.com" and found the waitlist got cleared. Called back, and I got my seat assignment.

I look up the sticky, it seems that LH454 has no flynet. But I hope though that I will get the PJs, since I did not get PJs and amenity kits for MUC-SFO two weeks ago ...
