Maybe someone has a good tip to offer here. I have a complex OW award that includes the segment Cusco - Lima (guess where we are visiting).

The only flight for which award seats were loaded to AA, the airline from which I booked the award, were the last flight of the day (LP38). Cusco is notorious for weather issues in the afternoon that cause cancellations of flights. My connections homeward are that same evening from Lima, which would multiply the consequences of any cancellation. LP has at least six other flights that occur earlier in the day, any of which would increase my comfort as there would remain a later flight such as 38 as a fallback. However, no inventory was available on any of those flights and none is found any time I call AA to check.

Expertflyer does not have access to the hidden bucket code T that is used for award trips.

A tip I found elsewhere suggested that I could use the LAN web site, after registering, to check for award seat availability. I did that and it seemed that most of the earlier flights still had seats open for awards, yet when I immediately called AA they found zero inventory.

It seems, based on this, that LAN does not make all award inventory available to the OW partners, or at least not to AA. That leaves me once again unable to watch for or set up an alert of any kind for when or if those seats are gifted by LP to OW travelers.

With AA metal, the EXP line can at least send a request to RM to consider opening inventory, but they are not able to do so with partners in OW.

Anyone have a technique that works, outside of simply pestering the EXP line every few days between now and July 1 when the flight takes place?
