The U.S. Department of Transportation's (DOT) Bureau of Transportation Statistics (BTS) tracks the on-time performance of domestic flights operated by large air carriers. Summary information on the number of on-time, delayed, canceled, and diverted flights appears in DOT's monthly Air Travel Consumer Report, published about 30 days after the month's end, as well as in summary tables posted on their website.

This dataset depicts flight delays and includes various attributes that can be analyzed to understand the patterns and causes of these delays. Each row in the dataset represents a single flight, providing detailed information that can be used to analyze the factors contributing to delays. For instance, the dataset can be used to determine which airlines have the most delays, what times of the day or week delays are most common, and what specific causes (such as weather, carrier issues, or security) are most frequently responsible for delays.

Overall, this comprehensive dataset serves as a valuable resource for analyzing the operational efficiency of airlines and airports, ultimately contributing to enhanced management and planning in the aviation industry.
