FARECAST says, “Our airfare prediction shows if fares are rising or dropping . . . Our Rate Key indicates whether or not today's rate for a specific hotel is a deal. It compares an individual hotel's current rate found to its observed historical rates.” And it now lets you compare its prices with those of other “travel bargain” sites.

     The SIDESTEP.COM search engine claims that "We search over 150 travel websites to bring you the very best travel values on the web." As I understand it, SIDESTEP does not purchase your tickets. You need to do that in a separate transaction.

     But TRAVELOCITY.COM will not only buy your tickets, it will take care of you, the whole trip through.

     TRAVELOCITY even has a “Customer Bill of Rights” – your rights – that include a live person to help you, 24/7:

     CHEAP TICKETS also offers deals. They seem to specialize in student discounts, such as cheap volunteer vacations in the Caribbean, though they have other bargains too. And they have a new feature: cheap tickets to sports events, concerts, etc.
