Build me a Streamlit app for airline route forecasting and network analytics.

I want a business intelligence dashboard where an airline team can upload or load historical flight data, store it in PostgreSQL, and explore route level performance in a clean executive view. The app should forecast passenger demand by route using time series models like ARIMA and exponential smoothing, then show accuracy scores like RMSE, MAE, and MAPE so people can trust the results.

It should also include route analytics for load factor, revenue, delays, and contribution by city pair, plus simple recommendations that flag where to add capacity, change frequency, or expand service. Make it easy to export charts and reports to CSV, Excel, and PDF.

Use the sample flight dataset fields already in the project if that helps, and keep the UI polished and easy to use. If you need current docs for any library, look them up online.
