Thank you all for your suggestions and calculations on how to figure this out. I really appreciate it.

I will try to find a cheaper ticket, but so far, because I fly from small (and expensive) market MFR, I can't find anything under $1050 to FRA - but then I still have to get to MUC, so that will add at least $100 by train. My miles are on Mileage Plus.

If I can't find a ticket cheaper than $1200, I'll go ahead use the miles.
