I did not want to use them to bid for airfare because you usually get the crummy times. But they have the feature now where you pick the times that they have listed, and they had a good selection of times. Last December I got airfare through USair for $116.50 and I figured I would not even get close to that this year with the cost of fuel etc, so when a co-worker told me he had seen the airfare for $123.85 I booked right away.
