Book Description
When both an industry's workers and its customers report high and rising frustration with the way they are being treated, something is fundamentally wrong. In response to these conditions, many of the world's airlines have made ever-deeper cuts in services and their workforces. Is it too much to expect airlines, or any other enterprise, to provide a fair return to investors, high-quality reliable service to their customers, and good jobs for their employees? Measured against these three expectations, the airline industry is failing. In the first five years of the twenty-first century alone, U.S. airlines lost a total of $30 billion while shedding 100,000 jobs, forcing the remaining workers to give up over $15 billion in wages and benefits. Combined with plummeting employee morale, shortages of air traffic controllers, and increased congestion and flight delays, a total collapse of the industry may be coming. Is this state of affairs inevitable? Or is it possible to design a more sustainable, less volatile industry that better balances the objectives of customers, investors, employees, and the wider society? Does deregulation imply total abrogation of government's responsibility to oversee an industry showing the clear signs of deterioration and increasing risk of a pending crisis? Greg J. Bamber, Jody Hoffer Gittell, Thomas A. Kochan, and Andrew von Nordenflycht explore such questions in a well-informed and engaging way, using a mix of quantitative evidence and qualitative studies of airlines from North America, Asia, Australia, and Europe. Up in the Air provides clear and realistic strategies for achieving a better, more equitable balance among the interests of customers, employees, and shareholders. Specifically, the authors recommend that firms learn from the innovations of companies like Southwest and Continental Airlines in order to build a positive workplace culture that fosters coordination and commitment to high-quality service, labor relations policies that avoid long drawn-out conflicts in negotiating new agreements, and business strategies that can sustain investor, employee, and customer support through the ups and downs of business cycles.

Book Description
Annual U.S. air travel demand has been growing steadily by 4-5% over the last decade, and it is estimated that the demand will nearly double in the next twenty years. It has also been estimated by the International Civil Aviation Organization that global demand for commercial aircraft will increase at an average annual rate of 4.1% by 2034 (IATA, 2014). However, airport expansions and aviation infrastructure upgrades have not kept pace with the increase in air traffic demand, as only 3% of all the new airport projects around the world are planned in the U.S. (CAPA, 2015). Thus, the operation rates at existing airports are likely to increase significantly, implying a greater need to increase the utilization of currently available runway capacity. With steadily increasing demand in air traffic and limited airport capacity, delay in air traffic is ubiquitous. Approximately 25% of flights experience delays of at least 15 minutes each year, resulting in significant passenger service issues and costs to airlines and society in general. Delays constitute the top service complaint for airlines, which has implications for the society as a whole - both economically and environmentally. Flight delays also increase airline costs directly, due to associated additional fuel, crew and maintenance costs. Recent studies show that the estimated cost of air transportation delay to the American economy ranges from $32.9 billion to $41 billion a year, of which, $8 billion are direct costs to airlines (Ball et al., 2010; Ferguson et al., 2013). Noting that more than 60% of delay is due to airport operations (Balakrishna et al., 2010), this thesis aims at helping reduce delay through better management of arrival and departure operations at airports, which can create relevant and significant value for the airlines and for the society. Arrival and departure operations inherently involve significant uncertainty. When an aircraft is approaching the runway, many factors affect its trajectory, such as weather, wind conditions, pilot behavior, aircraft weight, as well as the differences in types of aircraft and flight management systems. When an aircraft arrives at the gate, operating conditions, such as unplanned security checks, varied durations of deplaning and boarding, as well as the maintenance and fueling involved, could contribute to variations of actual departure time for the next flight. All of these stochastic factors involve uncertainty and they need to be taken into account while making operational decisions. On the other hand, stochastic treatment of such operational problems has not been common in the literature due to difficulties associated with the characterization of uncertainty and the computational tractability. I argue in this thesis that, with recent advances in computing power and data analysis tools, such stochastic treatments are more amenable for practical use. To this end, I study four novel operational problems related to flight arrivals and departures at airports under the uncertainty of operating conditions, and demonstrate the potential value that can be generated through stochastic models within the context of airline and airport operations. The problems I study involve both strategic and tactical decisions for airline service improvement and cost reduction. The first two problems consider managing arrival operations at airports, while the last two problems focus on departure operations. In the first and second problems, I focus on arrival operations in the context of optimized profile descent (OPD), which is a novel arrival procedure for the Next Generation Air Transportation System. In the first problem, I identify policies for managing arrival operations at the tactical level by developing a stochastic dynamic programming framework to manage the sequencing and separation of flights. I find that simple calculation based measures can be used as optimal decision rules during such operations, and that the expected annual savings can be around $29 million if such implementations are adapted by major airports in the U.S. Of these savings, $24 million are direct savings for airlines due to reduced fuel usage, corresponding to a potential savings of 10-15% in fuel consumption over current practice. I also find that optimal spacing of OPD flights is much more important than optimal sequencing of these flights. Furthermore, there is not much difference between the environmental costs of fuel-optimal and sustainably-optimal spacing policies. Hence, an airline-centric approach in improving OPD operations is likely to be not in conflict with objectives that might be prioritized by other stakeholders. In the second problem, I study the optimal design of arrival traffic management systems at airports at the strategic level. I claim that implementation of OPD operations requires effective metering configurations at airports due to the increased role of uncertainty in aircraft trajectories during descent. I develop stochastic models to further increase the value of OPD operations over conventional arrival procedures by optimizing metering point configurations, which include identification of the optimal number and locations of metering points to use. I provide numerical results based on actual traffic information at major U.S. airports, which indicate that the total potential savings in the top ten major airports could be up to $22 million per year if the proposed policies are implemented. I also find that the optimal metering configurations are mostly robust under different operating conditions. In addition, my results suggest that early spacing adjustments near the top of descent (TOD) are of more value for larger volumes of air traffic. In the third and fourth problems, I study optimal departure operations at airports under the context of departure metering, which is an airport surface management procedure that limits the number of aircraft on the runway by holding aircraft at a predesigned metering area. More specifically, in the third problem, I develop a stochastic dynamic programming framework for tactical management of pushback operations at gates and for determining the optimal number of aircraft to be directed to the runway from the metering areas. I introduce four easy-to-implement practical departure metering policies and implement a comparative analysis between these practical policies and the optimal numerical solutions. I also implement sensitivity analysis of the departure metering policies over state variable values. In the fourth problem, I study the optimal metering area capacity at the strategic level. Building on the dynamic programming framework mentioned in the third problem, I identify the optimal metering area capacity using marginal analysis to minimize expected overall costs. Numerical simulations are implemented and potential savings are identified for sample U.S. airports based on varying capacity levels. The optimal metering area capacity is then determined based on the numerical implementations to further improve overall efficiency and sustainability of departure operations. I also analyze the benefits to airlines in terms of annual savings due to such policies, and find that the annual savings could be $31 million if the optimal departure metering policies are implemented at the top ten major airports in the U.S. Overall, as one of the few studies on stochasticity in arrival and departure operations, I derive both tactical and strategic policies to improve efficiency and sustainability for airlines and the society, which can enhance service quality and strengthen market position for the airlines involved.
