Is there an option to keep past itineraries?  I find it helpful to review my recent travels when filling in my expense report for the month and having a place to keep my old itineraries would be a great addition to your already awesome product.  Hopefully it would be a relatively easy option to add, and you could just have a tab for "past itineraries."

Thanks for making our travel lives so much easier with Tripit!

Warm regards,
