Having googled searched, I haven't, unfortunately, got the difference between their usage. Would you please let me know the differences, and what they include in real life? (I mean, as travel options/terms...)
I don't see how you could have a choice between the two words. An itinerary is a detailed plan for a journey, especially a list of places to visit. An expedition is an excursion, journey, or voyage made for some specific purpose, as of war or exploration. You might say that the itinerary is the schedule for the journey, while the expedition is the journey itself.
