✈️ Airline Delay Analysis — End-to-End BI Project

A fully end-to-end Business Intelligence project built on the **US Airline Delay Causes** dataset. The project covers everything from raw data ingestion and cleaning in Python, through data modeling and dimensional design, all the way to interactive dashboards in Power BI — with no shortcuts taken at any stage.

The goal is to uncover the patterns behind flight delays across airlines, airports, and time periods, enabling data-driven decision-making through clear and interactive visualizations.
