Flight Search made easy, Really!! : Hipmunk

Hipmunk is a flight search engine with just one goal, save your time figuring out which flight to choose and let you choose instead.  When you make a search the result at first glance gives you clear idea on how much time each flight will take which is one of the important factors while choosing a flight. They use an algorithm, Agony which uses a combination of Price, Duration and number of prices.

Features :

• Search result in just one page.
• Lets you compare flights one with other.
• Hovering over one flight gives you detail of transit.
• You can also sort according to factors like price, stops, departure time etc.
• Tabbed interface makes it really easy when you want to book return tickets.
• You can also make searches on different tabs.

Check out Hipmunk, Thanks Matt.
