If I understand what you are looking for, Traxo will do it. I used Traxo for a while but decided I like TripIt better. I setup "rules" on my email to automatically forward emails with certain criteria to TripIt, then get that email out of my inbox. That way I don't have to deal with the addtional emails or remember to forward stuff to Tripit. This only works if you are pretty brand loyal, or have lots of rules.
