just got on LAN web site, requested award availabiliy Cusco to Lima for 3 passengers, came up with four flights stating definite avialability -- LP20, 22, 24 and 26. Called EXP desk, no availability shows.

Agent tried to get it pursued, but after a while hold, she came back and said that she HAD to book it thru the direct link and therefore her hands were tied. I tried asking about OW liason that I could talk to or mail, but got nowhere. The agent saw one flight on the next day open, so the link is working, just to eliminate that cause from the list of explanations.

Seems to me that LAN does not offer all inventory to OW, keeps some for its own FFs. Maybe when every non-status and premium FF is done, there might be a seat left for an Emerald from another airline, but I will have to brute force call incessantly since we haven't found any system that will spot availability.
