Very helpful!
I have TripIt set up to automatically scan my email inbox, and it works great! Really helps me to stay organized, esp. as I like to book multi-leg trips on my own so its all separate flights, hotels, staying with friends, etc. Only request for improvement would be better parsing of emails in German. Most the time I end up having to input these myself, as TripIt is unable to extract the data.
