TripWatcher.com sends alerts for airfare changes on routes you choose. An offshoot of the popular booking site Hotwire.com, it gives you the lowest rates in real-time via e-mail, Twitter, or Facebook.
Pintrips.com “acts like a digital bulletin board” by letting users compare flights from multiple sources. Instead of opening multiple browser tabs for Orbitz.com, Delta.com, etc., view all fares on one page.
Routehappy.com targets those interested in more than just price. You can search flights based on details like the age of the plane, Wi-Fi availability, legroom, and in-flight entertainment options.
GetGoing.com provides deep discounts for those willing to gamble. Choose two different destinations, and the site picks one of them, saving you up to 40 percent. The drawback is that tickets are nonrefundable.
