Multi-city itineraries are travel plans that include visits to multiple destinations within a single trip. These itineraries allow travelers to explore various cities, often within the same country or region, maximizing their travel experience. They can be customized based on interests, such as culture, history, or cuisine, and can be arranged through airlines, travel agencies, or online platforms. Travelers can benefit from multi-city itineraries by saving time and money, as they often provide better rates than booking separate one-way flights. Popular routes may include major cities like New York, London, and Paris, allowing for diverse experiences in a single journey.
