When you forward an email to them ([email protected]) they parse it and make a new trip for it. So each email creates a new trip.

Then, if you have auto-merge turned on, supposedly they combine related trips into one master trip.

So if you have a roundtrip flight and a hotel at the center point of that itinerary, those two emails should combine into one trip in theory.

Mine don't appear to ever do that. But I can do it manually.

In TripIt, you start by defining a trip via location and dates (NYC, 12/1-12/10, for example) and anything in that date range, when forwarded by email, ends up as part of that trip.
