If you want to play the game to only transfer miles after your reservation is confirmed, and you choose not to pick up calls from CX because you don't pick up unknown numbers, you are playing this game in a very risky manner to begin with.
Might be wrong here, but isn’t TTL set at the PNR-level (instead of the segment level)? I didn’t recall my upgrade requests having a TTL (they seem to stick there until after departure if they don’t clear). So my point is the confirmed upgrade have to be manually cancelled by an agent, not via an automatic process?
