Welcome to posting, starlite1000. I just looked at award availability using your AA miles. There is availability at 32.5K miles for the outbound on Sat, Aug 31, but not Friday, Aug 30. There is no availability any time surrounding your desired return. The first 32.5K award is available is Sept 9. I also looked out of San Diego since we have the nonstop JAL flight now that can be booked with AA miles. There was no better story with SAN as the originating airport. Should AA have been available, you would have needed 65K miles RT.

AA miles can be used for one way awards. Unfortunately, both Delta and US require RT redemptions. Thus, you can't grab that AA seat (after getting 2.5K more miles) and then find a return using your DL or US miles.
