A flight itinerary is a detailed plan that outlines the specifics of a flight journey. It typically includes information such as the departure and arrival cities, flight numbers, dates, and times. Travelers receive this document when booking a flight, and it serves as a confirmation of their travel plans. In addition to flight details, a flight itinerary may also include information about layovers, connecting flights, and baggage allowances. It is an essential tool for travelers, helping them stay organized and informed about their upcoming trips, whether for business or leisure.
