Overview

The Swiss Airlines Customer Support Assistant is designed to handle various customer queries and tasks related to flight bookings, car rentals, hotel reservations, and trip recommendations. It uses a sophisticated dialog management system to route user requests to specialized assistants for specific tasks.

Key Features

1. Multi-task Handling: The assistant can handle various tasks including:

   • Flight information and updates
   • Car rental bookings
   • Hotel reservations
   • Trip recommendations and excursions

2. Specialized Assistants: The system uses dedicated assistants for each task type, allowing for more focused and efficient handling of user requests.

3. Dynamic Dialog Management: The dialog flow is managed using a state graph, allowing for flexible routing between different assistants based on user needs.

4. Database Integration: The assistant interacts with a SQLite database to fetch and update information about flights, bookings, and other travel-related data.

5. Safety Measures: The system implements a two-tier tool system (safe and sensitive) to ensure proper handling of critical operations.

6. User Approval for Sensitive Actions: Before executing sensitive operations, the system requests user approval, adding an extra layer of security.
