FLIGHT DELAY ANALYSIS
POWER BI | DAX | POWER QUERY | BIG DATA
Analyzed more than 30 million U.S. flight records to identify delay patterns, root causes, and operational trends. Optimized Power Query performance for large-scale data and built an interactive Power BI dashboard covering on-time performance, delay causes, airline performance, and trends over time.
KEY INSIGHT
79% of flights were on time, while more than 73% of total delay minutes were mainly driven by late-aircraft and carrier-related delays.
