LAX-HKG 8/30-9/2 - Purchased P, then SWU to biz. The flight posted as C with 1x EQM and did not automagically fix itself. I gave it 3 days and then called to get it fixed. The call took about 5 minutes of the agent cross-referencing tickets, but from my side the process was painless. It probably helped that I still had the email with the original ticket number
