CO Website now displays fare class availability [non-preview site]
Not sure if this was posted yet or not... I did a quick search and didn't come up with anything, so if this is redundant, I apologize.
I noticed that the CO booking engine now has fare class availability info (click Fare Class then you'll see J9 Y9 B9 and so forth). I know this was made available on the preview site, but it's now on the official website. ^
