No SWUs on award flights.
I would look for other flights with award availability from the US to Europe and a connecting flight direct to Munich (even if you have to pay for the short Euro flight).
Check all the AA gateways to various cities in Europe. DFW, MIA, LAX, ORD, JFK, RDU. LHR, DUS, CDG, MAD, BCN, HEL, FCO, MXP
Good luck.
Great advice. And even consider trains as well within continental Europe. Went to Oktoberfest last year. Had to meet my brother, cheapest option from DFW was to HAM - took a train to MUC after meeting him. Quick, efficient, cheap.
Good luck once again.
