Select events on the calendar. They group themselves into trips by city, you set the exact travel dates, and it prices live flights and hotels against your ticket costs — itemised, never rolled into a single opaque number.

Itinerary
Events group into stays, and consecutive stays away from home become one trip. Drop a home-city event in the middle and the plan splits into two trips automatically — then it prices flying home against staying put so you can see which is cheaper. Every date is editable, including how much of each event you actually attend.
