You may have recently received an email invite from me to join and connect to me thru a new site called TripIt (www.tripit.com) . Although I think the social networking aspect of TripIt is pretty cool, and I would like to connect to you if you want, I am more impressed by their technology. This is an impressive application.
If you are like me and travel a lot, you understand how difficult it is to organize, and make readily available, your travel itinerary, especially if your trips include multiple flights, cities, hotels, etc. It is just difficult. This site does it perfectly.
All you do is send a copy of any confirmation email you have, from your airline, hotel, car rental, or travel site like Travelocity to plans@tripit.com. It figures out who you are, parses the appropriate information from the email, and creates a beautiful iternary for you, and in seconds. Here is a sample which I created by simply forwarding Southwest confirmation emails from previous trips:

Another cool feature is the “TripIt To Me” feature. If you want to retrieve any part of your itinerary while on the road, simply send an email to plans@tripit.com with a specific keyword in the body, and TripIt will decipher the request and return the info via email. For example, an email with “get trip” sent will return your entire trip itinerary in seconds. Here is a Wallet Card Command List they provide:

So, its these features that excite me the most. The social features are nice as well but pale a bit in comparison to the above technology. You can share trip details with others, view their trip info if they invite you, see who will be in the same place while your there, see who has trips coming up and to where, and see how much other people travel… all nice, but not earth shattering.
Thks!
