At OLCI the other day, DEN-SAN segment offered for $139. I was #10 as a Plat with PP applied and 2 seats left. No chance of clearing. Took the offer. Not the greatest value on a 2 hour "snack" flight but turned out to be the right decision after enduring 3 hours of literal butt hurt in Y on the previous 3 hour CLE-DEN segment that was offered at $414.
