AA has a codeshare agreement with Interjet, which covers quite a few Mexico destinations that AA doesn't operate. When I search aa.com for revenue tickets, everything is good. Route: OAX-MEX-LAX.

When I search for award tickets I get this message "There are currently no awards available on AA.com for your requested Origin and Destination. Please modify your request or contact AAdvantage Reservations for award opportunities on all AAdvantage participating airlines."

Is there really no way to redeem tickets for this award even though they are 'American' flights, or if I call, will they be able to see availability?

Thanks!
