97 people on a 739 SFO-ORD last Thursday evening, w/ F checked in full. I was in the mid 20s on an L fare. Probably not the longest list ever, but considering the size of the Y cabin (147), that's 66% of the Y cabin on the UG list when the doors closed. Further, since 3 people cleared, that's a 3% UG rate on the flight.
