means A planned route or schedule for a journey, listing the places you intend to visit and when.

from From Latin itinerarium, 'an account of a journey,' built on iter, itineris — 'a journey' or 'a road.' The same root walks quietly through 'itinerant,' the wandering traveler. It came into English in the 1400s, first describing actual travel writings before settling into the planning sheet we clutch at the airport.
