Again, this goes back to the original post's question, what is the priority of birthday upgrade?
Another point I find for birthday opups is that they generally find out ur birthday when they check ur passport but I also seen the system prompt the agent.
It is a difficult one but I thought the chance DM will get first for normal opup as they can predict oversell situation much earlier than whether a members birthday,
