I just tried Tripit for a 9-segment itinerary plus two hotels. I must say that the final merged page looks so cluttered with icons and spurious information that it is almost useless.

I have to send the itinerary to many persons who need to know the arrival departures times and flight numbers. However, they don't need to know the PNRs: remember, those can be used to change a booking. These people also have no desire to learn about weather in those cities, attractions there, or about hotel options I have not booked. They also don't need to know the phone numbers for various hotels and airlines.

I was looking forward to a neat uncluttered compilation of my flights in chronological order, at least as an option if not the default. In the end I ended up making my own with copy+paste from confirmation emails into a text editor.
