FL is known to begin boarding early, and I hate to ask for an u/g after boarding has started (even if that's when the 40-minute window opens).

Here's an update from this morning:

MKE-SFO flight 342 on 8/17/09
Unsuccessful. Approached GA about an hour before the flight to assess availaility and was told BC was full.
