Travelocity boasts what should be a brilliant tool: The ability to search for the best priced airfare between two cities, assuming your dates are flexible. Trouble is, after getting a nice long list of what appear to be great fares, the system gives you an error 95% of the time when you click on one.

"Sorry, that fare is no longer available". Well, then why did you tell me about it? I would happily wait a few seconds longer for my query to process if it meant I didn't have to click on 9 consecutive false leads. Bah.
