This is a service I use fairly regularly.  It allows you to forward the confirmation emails from your travel providers to the TripIt.com and they will automatically add the details to your itinerary.

From TUAW:

Tripit.com imports and interprets your itineraries from airlines, hotel chains, ticket outlets, and other travel companies. When you receive an itinerary from one of these providers, you forward it to a special Tripit email address to have it translated into a trip plan automatically (the site supports hundreds of travel providers, and the translation from email into structured itinerary is really quite amazing). You can share your travel plans with friends or colleagues via LinkedIn, and see when your fellow travelers are heading to a city near you or when their plans align with yours.

That collection of trip plans is what you view with the Tripit.com app. The app is linked to your Tripit.com account, and displays a day by day list of flights, car rentals, and other events that make up your trips. Each event can be opened in further detail to show information such as arrival and departure times, confirmation numbers, and more. Links for airport codes bring up Google Maps of the airport vicinity, and other links can check your flight status with a touch.
