Hipmunk, a relatively new flight search engine that displays results via a special “agony” factor, has finally made an iPad-compatible version of its app (ie, it’s a universal app now). One extra feature of the iPad version is Hipmunk’s much-beloved slider, which can quickly change the filtering of results by time of day.
Other features of the app include the usual filtering of results by price and number of stops, re-running of recent searches, and emailing booked flights to friends using the app.
Hipmunk is a free download from the App Store.
