Since your upgrade has cleared, if you go to a kiosk or agent, you will automatically be added to the first class standby list as well.
Note- You will be at the back of the pack of any confirmed passenger who is still waiting on an upgrade to first.
So if you are a plat, a gold who is confirmed on the earlier flight will get upgraded before you.
