If you like Kayak.com for its no-nonsense interface, you’re going to love Hipmunk.com. Its ultra-lightweight, barebones interface makes finding available flights easier and, we think, much more intuitive by displaying results as colored rows on a timetable.
The usual sort options are available: price, stops, departure time, arrival time, and duration. The site also allows for “tabbed” searching so you can keep multiple queries open and flick through them one at a time.
As Grant Martin noted however:
Running a quick search for an upcoming itinerary from ORD-CDG that we’ve got on the calendar, the proof is in the pudding. Hipmunk returns an (Orbitz available) $823 for roundtrip fare, while metacrawler Kayak (that actually queries aerlingus.com) returns $796.
Sure, it’s not perfect, but it’s definitely a site to watch. I can almost guarantee that other travel meta-search engines will be adopting this interface as a browsing option in the coming months.
