What has been happening in the last several months has been my upgrades clearing around 10-11 AM.

I am a platinum and it has been everywhere from day 4 to airport checkin.

It has been a while since I have had an upgrade at "just before midnight" on the fifth or sixth day, depending on how you count.

Just a point of information, from my experience. I am currently waiting on a few upgrades in the next 5 days that have "F" inventory, but no EUA running.
