Note that AA's program permits a free stopover at the North American "gateway" on international awards, so one could fly LAX-JFK/MIA (stopover) - DUS/TXL for as little as 20K AA miles one-way during the off-peak season. In addition, AA's partner Air Berlin offers seasonal nonstop service between LAX and Germany.
However, for free award flights in Economy between LAX and SFO (on AA) or YVR (on AS), British Airways Avios provide the best value.
