What were your experiences? I'm debating--could save $40. on airfare but they don't tell you times or airline until you purchase the ticket. For that I could go to priceline and try for even cheaper, right?
You should go to the biddingfortravel.com website, there is info there. I can tell you on most of the tickets that I priced on Hotwire I was able to get them for at least 40% less on Priceline.
