Electronic Travel Systems (ETS) are digital platforms designed to streamline the process of travel planning and management. They often include features such as online booking, itinerary management, and real-time updates on travel conditions. These systems can be used for various types of travel, including business trips and leisure vacations. Many ETS integrate with other services, such as airlines, hotels, and car rental companies, to provide a comprehensive travel experience. Users can access their travel information from multiple devices, making it easier to stay organized and informed throughout their journey.
