Hello, I am experimenting with the Name Your Price feature on Priceline.com and have been given a very cheap offer of a round trip flight from Chicago to Vegas for $150 on the 18th of December. It says in the information: "If we find an airline that accepts your price, we'll immediately purchase your tickets using the payment information you provided." Despite being offered the $150, if I pay this non-refundable fee, am I guaranteed to get on a flight on the days mentioned? Or is it possible for me to pay this and then them not able to get me on a flight? I cant quite tell from how it is worded and any help is appreciated. Thanks! Matt
