Expedia has released a major update to its TripAssist application designed to help travellers with booking, researching and tracking travel information. In addition to syncing itineraries from Expedia.com, TripAssist 2.0 allows users to enter and track non-Expedia travel itineraries as well. Other new features in the update include free real-time SMS and e-mail alerts for any flight, a new landscape-mode “billboard” view and a “date view” that consolidates all of the user’s itineraries into day-by-day listings. Users can also quickly look up alternate flight information, view a SeatGuru seat map for any flight and add their own notes to any itinerary. TripAssist requires iPhone OS 3.1 or later and is available from the U.S. App Store as a free download.
