You can attempt to do it online at anytime after you receive the "fairly full" text message; you can also try calling reservations if you don't want to wait and want to see if they'll give you an alternate routing without fare difference, etc.
Beware that any alternatives are likely to either already be or become just as full, if not fuller. When I've looked at my flights (purely out of curiosity) the next available option may be 24 hours out and very similar loads... obviously with a major trunk route like SFOEWR there are more options, but I wouldn't expect any of them to be less than 70% based on what I'm seeing generally.
