UA has a $200 base fare from NYC-MUC (that I don't think they had a couple of days ago) in L class. Strange applicability - US to Europe on Sun-Thurs, while Europe to US is allowed Mon-Thurs. Saturday night minimum, so it doesn't allow an immediate turn.

Without trying too hard, you can get this on all UA metal (if you so prefer) for under $400 ai. I'm sure the folks that are really good at this can do much better. At first glance, the SFO and LAX folks don't seem to have a similar fare offered on this one.
