So, this has been a huge mess + 10~ phone calls to figure out (though half of those never reached an agent thanks to the mess at AC right now).
What happened was when the AC flight schedule changed, my LifeMiles ticket was taken over by Air Canada (which is not what should happen; it is a known issue with AC likely because of their new system).
So, my 134 Avianca Lifemiles ticket became a 014 Air Canada ticket. Avianca would claim every time I called it belongs to AC and they can't touch it which seemed wrong, but the last time I called AC the agent confirmed they did own it (contrary to the prior agent I spoke with) and that it was a known issue in their system and they would handle it manually. They accommodated me by adjusting my final flight to be after my first two flights rather than before it.
