Sam3305/FlySAND ? reverse-engineered prompt

Build me the FlySAND app, an AI managed airline simulation for the India trunk routes between Delhi, Mumbai, Chennai, and Kolkata.

I want a web app with a simple booking portal for customers, plus separate dashboards for operations, finance, and an agent control view. The system should show live seat availability, booking history, and changing ticket prices based on demand, weather, and basic route economics. It should also have a backend that handles flight data, bookings, live updates, and background price recalculation, with a safe way to stop double bookings.

Please make the UI clean and easy to use, and keep the main experience focused on booking flights and watching prices move in real time. If any setup details are missing, look up current docs online if you need to and wire it together in a way that actually runs. Use the existing project structure where possible, and make sure the frontend and backend connect properly.
