The Unsettling Sky: A Business Problem Unfolds
Our skies tell stories of triumph, but they also narrate the frustrations of flight delays and cancellations that have increasingly become a part of the modern traveler's experience. The figures are stark – with significant percentages of flights delayed, impacting lives, business operations, and the reliability of air transport. This analysis dives into the heart of this problem, seeking not only to understand the 'why' but also to forge a path to a solution.
Why This Matters: The Turbulence of Delay
Why This Matters: The Turbulence of Delay
The reasons are manifold. There's the personal experience – the countless hours spent waiting in lounges, the missed connections, the ripple effect of a single delay cascading through an intricate network of flights. There are the operational costs – for airlines, the financial repercussions are severe, ranging from fuel costs to crew overtimes. Then there's the customer's loss – tangible in terms of time and money, intangible in terms of trust and satisfaction.
Dataset
Dataset
Data downloaded from Kaggle's 2015 flight delays and cancellations dataset.
Originally sourced from U.S. Department of Transportation's Bureau of Transportation Statistics.
Turning to the past to understand the future, we focus on the year 2015 – a year of data that captures a microcosm of the broader issue. Kaggle's dataset provides us with the canvas – a detailed picture of the airline, airport, and flight details within the United States. Adding depth to our analysis, we've included the "aircraft tail numbers" dataset, and tethered to it, the "state.csv" enhancing our ability to draw insights with precision.
Our lens narrows further, zooming in on the Logan International Airport, Boston. A hub that epitomizes our challenge – teeming with air traffic, each day unfurling a tapestry of delays, a key player in the national picture with top airlines etching patterns of punctuality and delay.
We took the time to go through and pinpoint the main areas of interest in the dataset after conducting a comprehensive data exploration. In order to extract useful information, we developed a series of inquiries that we divided into two primary categories: airports and airlines. We wanted to learn more about the different facets of flight operations, such as airline performance, airport traffic, and possible causes of delays and cancellations, by answering these questions. These questions served as a roadmap for our investigation, enabling us to find important patterns and trends in the dataset. Now let's explore the disclosed information.

The insights unfold in colors and numbers on the dashboards. The bustling hubs like Atlanta and Chicago, brimming with routes, contrast with the singular focus on Boston, shedding light on how traffic volume shapes delays. As JetBlue and American Airlines weave their routes through Boston's airspace, the ebb and flow of delays across seasons become apparent, peaking in the summer and dipping in the quieter months.
At Boston Logan Airport, airline performance varies significantly in terms of cancellation rates and punctuality. Passengers flying with Delta Air Lines Inc. are more likely to face cancellations and delays compared to those traveling with American Airlines Inc., which maintains the lowest average delay time. The bulk of cancellations across all airlines is due to weather, highlighting the need for airlines to be proactive in dealing with seasonal weather patterns to minimize disruptions.
Late aircraft arrivals are the primary culprit for extended delays, suggesting a domino effect of scheduling challenges. Addressing this might require airlines to reassess their turnaround times and buffer between flights. Security, while a concern for travelers, does not significantly contribute to delays, indicating that airport processes in this area are efficient.
Throughout the year, the causes of delays fluctuate, with weather-related delays peaking during the winter months. Airlines could mitigate these effects by adjusting schedules and increasing communication with passengers during these high-risk periods.
The data presents a compelling narrative for stakeholders at Boston Logan Airport to examine the operational efficiency of airlines and develop strategies to enhance the reliability of air travel for customers. It also stresses the importance of robust weather management plans and suggests that improvements in managing aircraft turnaround could alleviate a substantial portion of the delays experienced by passengers.
Traffic is increasing, worsening delays
Traffic is increasing, worsening delays
A few things are directly within the carrier's control: crew and technical performance, passenger punctuality, aircraft turnaround times between flights, etc. However, there may be even more variables beyond the airline's control, like weather, airport circumstances, security, and air traffic control.
Flight delays are an inevitable element of traveling by air as long as aircraft are operating. The Bureau of Statistics estimates that 2095 out of every flight have a delay of at least fifteen minutes, and future increases in traffic will make the situation worse.
ARRIVAL AND DEPARTURE DELAYS ARE MASSIVE
ARRIVAL AND DEPARTURE DELAYS ARE MASSIVE
Delays and disruptions in airline operations annually result in billions of dollars of additional costs to airlines, passengers and the economy.
We can clearly see that the biggest causes of delays are Arrival delays and Departure delays that are caused while taxi in and taxi out of the aircraft.
Delays and cancellations affect both passengers and air carriers. By resulting in increased travel time and increased expenses on food and lodging, they cause streks among passengers. Further, they disrupt the purpose of air travel - rapid, affordable and safe - and make the passengers distrust airlines. On the other hand, airlines suffer from extra crew costs, costs associated with accommodating disrupted passengers, and aircraft repositioning , as airline fleet and the crew schedule a large delay over the scheduled times.
FLIGHTS CANCELLED ? WHY? LET US REVIEW
FLIGHTS CANCELLED ? WHY? LET US REVIEW
Weather:
Bad weather, common in winter, often leads to flight cancellations, with storms like hurricanes, blizzards, and tornadoes causing significant disruptions.
Air Traffic Restrictions:
Air traffic controllers may ask airlines to postpone flights, especially when delays occur due to limited time slots in departure schedules. These restrictions, increasingly common due to rising air traffic, are caused by the exponential growth in passenger numbers.
Aircraft Issues:
Mechanical Problems:
Flight delays or cancellations may occur due to necessary aircraft maintenance or repairs, with cancellation being the last resort if repairs cannot be completed promptly.
Aircraft Unavailability:
Flights may be canceled if an aircraft scheduled for the journey requires unexpected maintenance or servicing.
Crew Availability:
Flight cancellations can happen if scheduled crew members have exhausted their flying hours or face personal medical issues, leaving the aircraft without a crew.
Airline Cancellation Rate:
Delta Air Lines Inc. has the highest cancellation rate, followed closely by American Airlines Inc. and Southwest Airlines Co.
United Air Lines Inc. and JetBlue Airways have cancellation rates below the 2.188% average, suggesting better reliability.
Total Cancellation by Cause:
Weather is the most significant cause of cancellations, with 1,435 cancellations, highlighting its unpredictable nature and the need for robust contingency plans.

SOLUTION FOR DELAYS
SOLUTION FOR DELAYS
Dealing with Air Traffic:
Air traffic is one of the main causes of aircraft delays, and effective air traffic management can reduce the delays.
Reducing the Diversions:
The delays that occurred throughout the flight are directly correlated with the diversion rates. The deviations we observe in our data could be caused by a number of factors, including weather-related problems, system malfunctions, or security-related concerns.
Additionally, we can observe that the diversion rate is noteworthy for two carriers in particular: American carriers and Uniter Airlines. Consequently, there were halts and delays on the entire trip.
Increasing operation efficiency (Taxi in and Taxi Out) at airport:
There is a noticeable increase in airport delays. Since airlines are using smaller but more frequent passenger jets, there is more traffic at gates and on runways, which is largely to blame for these delays. Airport slots' for takeoff and landing will be auctioned off, reducing traffic. There would be various advantages to these auctions. They would create income to pay for airport upgrades and capacity growth, reallocate airport assets to higher-value applications, and encourage airlines to utilize airport space more effectively.
Increasing the Ground Staff Employees with respect to the Airport Volume:
Researchers determined that hiring more ground staff on Airport has tremendous effect on the overall delays caused while the airports with low proportion of employees. The traffic controllers and regulators basically help any aircraft to give adequate directions and ATC help to monitor any activity across the flights.
