I am a fan of Tripit I use it on a personal level to track and manage my travel itineraries. I simply email my travel information i.e. flights, accommodation and other bookings to tripit and it will build my itinerary. Via a web browser I can review and keep my travel information organised. On a smartphone I can view my itinerary. Via email I can get a download of my travel plans.
I have just downloaded Tripit to my new Android Tablet. I can see my whole itinerary with full details. I love it. In my less than humble opinion this has to be one of the best online services available for free for travellers.
The Bludger loves travelling.
