Priceline.com allows you to shop and compare great deals on flights, hotels, rental cars, vacation packages, cruises, last minute deals, weekend deals, and more.
Priceline is a buying service -- they allow you to "name your own price" for airline tickets. Priceline has deals with certain airlines to enable lower air fares on certain routes. As long as the price you name is higher than the price of the ticket, they add on associated fees, then you've bought the ticket.
