So I had an award put on hold, LIM-JFK(stop)-PHX-KOA. I called back today to book it and the LIM-JFK leg was canceled under the hood. I had a great agent who understood what happened, and put the award back together for me. She said that it was impossible to put a segment on LAN on hold, just due to how their systems interact. She also told me that Ibera segments can only be on hold for 24 hours. I was wondering anyone else had see or hit this issue. Also, you can in fact voluntarily downgrade for a the cross region flight on a business award if there is no availability it seems. Since the free one way is actually more valuable than the 'award' I was happy to put that together and wait the time for the seat to open up.
