Looking for strategy on upgrade + SDC:
I'm on a 8am flight with plus points applied, but I knew there was no chance of upgrading(J2).
There is also a 6am flight with P9. So I thought I could SDC when it becomes available and easily get upgraded. However when I woke up at 6am the day before, I realized the system had already cleared many people into J, so there is only J1 left.
I'm wondering if there is a better strategy to handle this in the future.
