TripIt.com takes the fuss out of trip planning
By partnering with professional networking group LinkedIn (which has more than 30 million members worldwide), TripIt.com has solidified itself as a leading trip management tool for business and leisure travelers.
TripIt puts an end to the annoying search for your flight, hotel, train, cruise and car rental confirmation numbers by building a master itinerary that contains all your travel info, maps, weather, restaurants and more. You can access the free service from e-mail, a personal calendar or a mobile device.
TripIt can sync my plans to the calendar feature on my computer or on my iPhone, and I can share my trip plans with a non-TripIt user (using a temporary account).
There are lots of cool features worth using on TripIt, but it takes a bit of playing around to figure it all out. Use the TripIt Help page for quick-start guides.
