OP: AA is currently asking for a large number of AAdvantage miles for award seats on that route on your dates. AA award seats are only available for redemption by partner programs when AA is asking a relatively low number of miles. While anything is possible, I would not be too optimistic about that happening for your preferred dates of travel. You can check AA redemption rates periodically on aa.com or the AA app (no AAdvantage account or login required). I would not expect to see Avios availability unless and until AA redemption rates fell to something like 10-15K.

Do you have/can you acquire some AAdvantage miles in the event that you won't be able to redeem Avios for the return?
