An integrated model of flight and passenger delay for policy analysis in the National Air Transportation System
… has increased over the years and so have airport delays and congestion. Delays have a huge impact on airline costs and influence the satisfaction of passengers, thus becoming an important topic of research in the field of air transportation. In recent literature, a Passenger Delay Calculator (PDC) …

Predicting Irregular Flight Operations Using a Binary Machine Learning Approach Based on National Meteorological Data
Flight delays are caused by a multitude of external influences as well as revenue driven carrier decisions. Some factors are obvious while others remain inaccessible to the traveling public. Yet knowing of potential flight delays or cancellations in advance can significantly improve passengers’ …

Essays on the industrial organization of the airline industry
… Chapter 1 investigates the effect of air traffic delays on airline prices. The degree to which prices respond to changes in service quality should depend on consumers' willingness-to-pay for quality, as well as the availability of substitute products. I study the effect of an exogenous variation …

From Tarmac to Timetable: A Data-Driven Study of Airline Delay Performance in Nigeria
… the patterns, causes, and impacts of flight delays in the Nigerian aviation sector from January 2024 to January 2025. Utilizing a dataset containing flight details—including scheduled and actual departure/arrival times, routes, and airline information—the study employs advanced data …

Modeling and Control of Networked Systems: Applications to Air Transportation
… air traffic has resulted in congestion and flight delays. Delays not only inconvenience passengers but also have negative environmental impacts and cause monetary losses for airlines. Reducing delays is therefore crucial for operating a sustainable, efficient, and robust aviation …

Minimizing airline passenger delay through integrated flight scheduling and aircraft routing
Statistics show that airline flight delays and cancellations have increased continuously over the period from 1995 to 2000. During the same period, customer dissatisfaction and complaints have followed a similar, even more dramatic trend. In 2001, as a consequence of the September 1 th terrorist …

Cost-Benefit Analysis Model for Advanced Weather Forecasting Installations in Airport Terminal Areas
… system capacities can significantly decrease delays, as well as number of cancelled flights. An efficient Air Traffic Control system equipped with advanced technology installations in the terminal area can help reduce flight delays and cancellations. The same technology could also help reduce …

Airline scheduling and air traffic control : incorporating uncertainty and passenger and airline preferences
… to adverse effects including airline losses, delays and disruptions. This thesis studies a set of topics in airline scheduling and air traffic control to mitigate some of these issues. The first part of the thesis focuses on building aircraft schedules that are robust against delays. We …

Simulating airline operational responses to environmental constraints
… describes a model that predicts airline flight network, frequency and fleet changes in response to policy measures that aim to reduce the environmental impact of aviation. Such airline operational responses to policy measures are not considered by existing integrated aviation-environment …

Approaches to incorporating robustness into airline scheduling
… that can occur during operation. The resulting flight delays and cancellations can cause significant revenue loss, not to mention service disruptions and customer dissatisfaction. A novel approach to addressing this problem is to design schedules that are robust to schedule disruptions and can …

Classification of summertime West Coast fog and stratus events and the development of fog and stratus forecast techniques
… life, the greatest impact on aviation. Many flight delays and cancellations that are experienced around the Pacific Rim are attributed to the development and evolution of the fog and stratus on the U.S. West Coast. This thesis studies the evolution of the fog and stratus events during the …

Essays on airport and airway congestion
… airspace congestion are the primary causes of flight delays in the US. These delays cost airlines and airline customers billions of dollars per year. This thesis consists of two essays. The first essay focuses on several of the commonly proposed market-based solutions to airport congestion. …

Empirical investigations of properties of robust aircraft routing models
… that can stand uncertainty. We categorize the delays in flight operations into two components – independent delay and propagated delay. In the data driven approach, independent delay can be regarded as constant, but propagated delay can be worked on. An example of aircraft swap is given to show …

Integrated modeling and simulation of lunar exploration campaign logistics
… and robustness to campaign level risks such as flight delays, flight cancellations and uncertain demand parameters. The significant findings presented in this thesis broadly fall into three categories: a demonstration of the value of integrated modeling and simulation of campaign logistics, the …

Design and implementation of a sector-based airspace model for the MIT Extensible Air Network Simulation
… and air traffic managers in predicting flight delays for given air traffic scenarios. One aspect of the simulation, the determination of flight times, has received criticism from the MEANS users as being too simplistic for their needs. Currently, MEANS predicts flight times based on a …

Robust airline schedule planning : review and development of optimization approaches
… potential and satisfy constraints involving flight schedule design, fleet assignment, aircraft maintenance routing and crew scheduling. Almost all aircraft and crew schedule optimization models assume that flights, aircraft, crews, and passengers operate as planned. Thus, airlines typically …

Spectral Models for Air Transportation Networks
… metrics reflect only the magnitude of incurred flight delays at airports. In the first half of the thesis, we show that it is also important to consider the spatial distribution of delays across a network of airports. We analyze graph-supported signals, leveraging techniques from spectral graph …

An application of design structure matrix methods to explore process improvements in aircraft fight line operations
… in troubleshooting and readying aircraft for flight at an aircraft manufacturer's flight line was analyzed using Design Structure Matrix (DSM) methods. Mapping the two DSMs together into a larger multi-domain matrix (MDM) provided insight to the ways information is transferred, and clarified …

Planning for robust airline operations : Optimizing aircraft routings and flight departure times to achieve minimum passenger disruptions
… plans based on the assumption that every flight leg departs and arrives as planned. Because this optimistic scenario rarely occurs, these plans are frequently disrupted and airlines often incur significant costs in addition to the originally planned costs. Flight delays and schedule …

Modeling and Control of Queuing Networks: Applications to Airport Surface Operations
… Airport congestion results in increased flight delays, fuel burn and emissions. There is consequently a need to accurately model airport traffic operations and to design control algorithms that mitigate airport congestion. In this thesis, we propose a new class of queuing network models …
