Travel search engine Kayak has launched a new version of its iPhone application.

According to a report filed by Techcrunch, Kayak’s paid app ($3.99) for flights on business or first class has also been updated with the trip management feature and improved search and UI. 

New features and upgrades include a two-dimensional desktop-style navigation system, an enhanced flight, hotel and car search design including a new scrolling calendar, faster search and additional search options and filters. 

The application also serves as an itinerary management service that consolidates flight, hotel, car rental, maps and other events into a single itinerary. 

For its free application, Kayak says it has had over 550,000 unique activated users so far.
