What is My Personal Calendar feed?
Your Personal Calendar Feed automatically adds your trip destinations, travel dates and the details of your trips to your calendar application. If you use a calendar that supports the iCalendar Feed (iCal) standard (such as Outlook 2007, Google Calendar, Lotus Notes, or Apple’s iCal, among others), you can sync the items in your TripIt itineraries to events in your calendar without having to manually re-enter all of the details. Even better, once you set up your calendar feed (which should take less than one minute), the information is automatically kept up-to-date via a live feed between TripIt and your calendar. Any changes you make in your trips from your TripIt account will automatically be updated in your calendar.
