Factors Influencing Airline Delays of United States

This article analyzes and studies the causes of airline delays originating in the United States. The aim is to find out the most significant causes of flight delays and help airlines better optimize routes and reduce potential losses. Previous studies have shown that the main causes of airplane delays are delays in the national aviation system and the airlines' own delays. This article uses linear regression to analyze the data. The conclusion is that the occurrence of aircraft delays may be related to factors such as National Aviation System, Aircraft Arriving and weather. While analyzing the factors that cause flight delays, the paper also analyzed the interactions between these factors and a strong correlation was found between Air Carrier Delay and Aircraft Arriving Late Delay, this may have contributed to the fact that the effect of Air Carrier Delay on flight delays was not significant enough for the analysis in this paper. In addition, Airline Diverted, Flight Cancellation, and Security Delay had very little effect on with flight delays.
