This is great news...for those of us frequently on 6:00 a.m. flights this translates into twenty minutes of extra sleep (i.e. I don't need to leave enough time to make sure I'm at the terminal :40 before the flight - :20 will do - in order not to get 'locked out' by the TSA).

Since I don't have a CO flight for a few weeks, I will be VERY interested to see everyone's report on how upgrade/standby works with this.
