I just discovered Priceline and was playing around with some scenarios to see how the bidding works. I found that whenever I offer a bid of $1, my offer is always accepted and the only thing that changes is the fees and taxes depending on the route I choose. For example, Buffalo to Singapore was $123.45 for the total trip cost. Buffalo to San Francosco was around $38.75. These are crazy cheap prices, is there a catch? I don't understand why anyone would want to bid more than $1? Thanks.
