TripIt is awesome
Sounds like a great example of software done right:
You know what I really like? TripIt.com. It’s amazingly simple. You take all those travel confirmation emails that you get from your travel agent, hotels, car rental agencies, etc, and you just forward them to plans@tripit.com. That’s all you have to do. You don’t have to sign up for an account. You don’t have to log on. You just forward those emails. You can do it right now.
You get a link back by email, with a beautifully organized itinerary, showing all your travel data plus maps, weather reports, and all the confirmation numbers for your flights and address for your hotels and so on.
