What is meant by the term "itinerary" in relation to air travel?

The term "itinerary" in relation to air travel refers specifically to a detailed schedule of flights that outlines the traveler's journey. This schedule typically includes information such as departure and arrival times, flight numbers, layover details, and the airlines involved. An itinerary serves as a crucial tool for travelers, helping them organize their trips effectively by providing a clear roadmap of where they need to be and when.

In contrast, a complete travel account would imply a narrative or overview of the travel experience, which is broader than just the flight details. A list of possible destinations indicates potential places to visit but does not provide the specifics needed for actual travel plans. Lastly, a record of baggage items focuses on what is being transported rather than the travel schedule itself. Therefore, the definition of an itinerary aligns most closely with the concept of a detailed schedule of flights, making it the correct answer.
