It's the massive difference between Y and J, and having to wait, watch, wonder at the inventory until the magic T minus 25 hour clearance occurs. The waitlists don't even clear until it's really close in for most flights. The only saving grace to AA SWUs is the ability to use them on every class, unlike UA. But with UA, they at least release a decent amount of upgrade space in advance.

In the end though, they are worthless, because I'd rather purchase W or J to have my expectations set instead of upending them for the better at 25 hours prior to departure.
