Is CoMETS a tracker of past itineraries?
Or evaluator of future itineraries?
Can you describe its purpose a bit better?

Feature request: Biggest plus would be able to cut an itinerary right out of several major websites (Expedia, Travelocity, AA.com, etc) and paste it into CoMETS, parsing it all out so the user doesn't have to do all of the parsing for the computer.

Sure, I'd play with a beta of CoMETS.
