EVALUATION OF AIRLINE EFFICIENCY AND ENVIRONMENTAL IMPACTS USING DATA ENVELOPMENT ANALYSIS By Arun Paul Saini A Dissertation Submitted to the College of Aviation in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Aviation Embry-Riddle Aeronautical University Daytona Beach, Florida August 2018 © 2018 Arun Paul Saini All Rights Reserved. ii ABSTRACT Researcher: Arun Paul Saini Title: EVALUATION OF AIRLINE EFFICIENCY AND ENVIRONMENTAL IMPACTS USING DATA ENVELOPMENT ANALYSIS Institution: Embry-Riddle Aeronautical University Degree: Doctor of Philosophy in Aviation Year: 2018 Airline efficiency has been a focus of research since the birth of the airline industry. Data envelopment analysis has become a highly accepted methodology for performing efficiency analysis and assessing relative differences between comparable business entities; over the last decade, airline efficiency research has proliferated into this linear programming domain. While early airline efficiency research focused primarily on revenue generation and profitability, growing commercial social responsibility is driving greater investment into understanding and improving the environmental impact of airline operations. This study is intended to partially fill a gap in exigent literature. While limited data envelopment analysis including environmental impacts has been conducted, the models treat environmental impacts as an output, never as an input or intermediate variable in the decision-making models. This study constructed a linear programming model utilizing the data envelopment analysis methodology to assess the relative efficiencies of thirteen airlines. The model consumes operational and financial performance indicators of the airlines, as well as abatement success measured as a function of the carbon dioxide emissions iv produced by the airline operations. The study analyzed airline activities from 2013 to 2015. The results of the study indicated that the linear programming model was successful in measuring airline operational efficiency, inclusive of: (a) different capacity and cost components of airline operations, (b) carbon dioxide emissions abatement, (c) differing airline business models associated with service levels, and (d) the implications of different routes and networks. Airline-specific recommendations are presented, based on analysis of their 2013-2015 operational performance reviewed in conjunction with airline strategy disclosures included in annual reports. The study provides theoretical and practical contributions to airline efficiency research. The study is the first to include environmental impact abatement expense as an input into airline decision-making for an overall airline efficiency model, as opposed to an output which is calculated as part of an optimization strategy focused on capacity or revenue generation. v DEDICATION I dedicate this work to my mother and father. Mom, your support and perpetual reinforcement have been the wind beneath my wings through this seven-year journey. Thanks for seeing this through with me. Dad, your memory and achievements continue to influence the course I plot. I will forever be blessed to have so much advice available to me, long after I lost the opportunity to ask you for it. vi ACKNOWLEDGEMENTS I would like to acknowledge everyone that made this dissertation possible. This doctoral program has encompassed a seven-year period, and I would not be at this point without extraordinary support in my academic, professional, and personal life. First, I must recognize my dissertation chair, Dr. Dothang Truong, for his mentorship and guidance over the last two years. His inputs have been invaluable to my strategy and execution of this dissertation. I would also like to express my gratitude to my dissertation committee members – Dr. Ahmed Adelghany, Dr. David Esser, and Dr. Matthew Fischer – for their feedback, thought-provoking input, and support. My career has carried me through three very different jobs at Gulfstream Aerospace during this program. In the positions I have held, it has required understanding and accommodation from my leaders for me to survive this journey. Chronologically, I must recognize the support of Mark Sells & Bill Bradley; Greg Collett, Becky Elliott, Jonathan Ringham, & Melissa Grant; and Steve Ritchie. My family and friends have accepted my absence over the last several years while continuing to provide love and understanding. My mother’s support has never wavered. The Saini-Shea’s have accepted my aberrant attendance to family gatherings; I hope my two nieces are too young to remember. The Atkinsons, Fosters, Pearlmans, and Shepards continued to include me as the friend they see every day, though I seemed to decline 95% of their invitations. Finally, a special thanks to Andrea Burkhardt for her support of the dissertation. In the last year of this program, she has literally taken on the responsibility of my day-to-day survival so I could focus on this work. vii viii TABLE OF CONTENTS Page Abstract ............................................................................................................................. iv Dedication ......................................................................................................................... vi Acknowledgements .......................................................................................................... vii List of Tables .................................................................................................................. xiii List of Figures ................................................................................................................. xiv Chapter I Introduction ................................................................................................ 1 Statement of the Problem ............................................................... 5 Purpose Statement .......................................................................... 6 Significance of the Study ............................................................... 6 Research Questions ........................................................................ 8 Delimitations .................................................................................. 8 Limitations and Assumptions ...................................................... 10 Definitions of Terms .................................................................... 13 List of Acronyms ......................................................................... 15 Chapter II Review of the Relevant Literature ........................................................... 16 Review of Research in Airline Efficiency ................................... 16 Airline Efficiency Utilizing Total Factor Productivity (TFP). ............................................................................... 16 Application of DEA in Measuring Airline Efficiencies. 19 Environmental Impacts in Aviation ............................................. 28 Environmental Motivations in Aviation. ......................... 28 ix Environmental Studies on Aircraft Operations. ............... 30 Environmental Impact Abatement Today. ....................... 33 Research of Airline Efficiency Inclusive of Environmental Impacts. ............................................................................ 39 Data Envelopment Analysis (DEA) ............................................. 43 Origins of DEA. ............................................................... 43 Multi-stage DEA. ............................................................. 56 Gaps in Exigent Literature ........................................................... 62 Summary ...................................................................................... 63 Chapter III Methodology ............................................................................................ 65 Research Approach ...................................................................... 65 First Conceptual Model – Theoretical Three-stage Model Design .............................................................................. 65 First Conceptual Model – Three-stage DEA Model Formulation ...................................................................... 70 Final Model – Theoretical Multiplicative Relational Two-stage Model Design ................................................. 78 Final Model – Multiplicative Relational Two-stage Model Formulation ...................................................................... 82 Apparatus and Materials .................................................. 86 Population/Sample ....................................................................... 86 Sources of the Data .....................................................................

  • Massachusetts Institute of Technology Flight Transportation Laboratory
    Massachusetts Institute of Technology Flight Transportation Laboratory Report FTL-R79-5 A SYSTEMS ANALYSIS OF SCHEDULED AIR TRANSPORTATION NETWORKS William M. Swan June 1979 FLIGHT TRANSPORTATION LABORATORY REPORT R79-5 A SYSTEM ANALYSIS OF SCHEDULED AIR TRANSPORTATION NETWORKS BY: WILLIAM M. SWAN - 1" 11 M- - ABSTRACT This work establishes the conditions for airline system design building from submodels of smaller aspects of air transportation. The first three sections develop submodels which then are combined in extensive numerical studies of singles market services. The final section discusses the changes to this problem that occur due to network effects. The first section develops a simple model of the cost of providing scheduled transportation on a link. The cost of aircraft of various capacities are divided into a per-frequency cost and a per-capacity cost for conventional subsonic turbojet designs. This cost structure implies that the more capacity provided in conjunction with a fixed schedule of departures the lower the average cost per seat. It is suggested that such aircraft scale economies create a trend toward monopoly or at least oligopoly services. The second section develops a model for demand. The market for transportation is argued to be the city pair. Demand for scheduled service is expressed in terms of fare, frequency and load factor. Fare, frequency, and load factor are combined into total perceived price for the service. This price depends on the consumer's personal value of time. With only a few competitors in aich a market, only a few of the tech- nically possible qualities of service will be offered.

  • Airlines and Subsidy: Our Position ¬
    Airlines and subsidy: our position ¬ Myth Airline subsidies are a “Gulf” problem FACT Market-distorting subsidies and government support are sadly present in every world region Myth Emirates is subsidised FACT Completely unsubsidised. We campaign against airline subsidies Myth Emirates accesses cheap or free fuel FACT False. We buy fuel from BP, Shell and Chevron in Dubai and worldwide at market rates Myth US and European airlines received support decades ago but are now subsidy-free FACT Bankruptcy protection and government bailouts continue to exist Airlines and subsidy: our position ¬ We understand that despite no evidence, an oft repeated myth can ultimately be accepted as conventional wisdom. In this document you will find our views on subsidy in the airline industry, thorough explanations about Emirates’ business model and our response to misrepresentations that have been levelled against us - from claims about subsidised fuel, financial support and staff conditions to environmental regulation and airport charges. Emirates believes: • A common set of transparent financial reporting metrics to measure and apply against all international carriers should be determined by IATA and ICAO on what defines a subsidy. • Governments should not provide injections, borrowings or financing to airlines, regardless of shareholding status. • All governments should pursue liberalisation and open skies with the objective to end the greatest subsidy of all – aero-political protection.

    Speech GENERAL MEETING OF DEUTSCHE LUFTHANSA AG – SPEECH BY THE CHAIRMAN OF THE EXECUTIVE BOARD AND CEO CARSTEN SPOHR 4 May 2021, virtual Lufthansa Aviation Center, Frankfurt To be checked against delivery. SPEECH: General Meeting of Deutsche Lufthansa AG – Speech by the Chairman of the Executive Board and CEO Carsten Spohr Dear Shareholders, I also welcome you to the Annual General Meeting of Deutsche Lufthansa AG. Unfortunately, for the third time only virtually, from our Group headquarters, the Lufthansa Aviation Center in Frankfurt. I speak for the entire Lufthansa Executive Board when I say that we would really have liked to welcome you in person today. But it was not yet to be. You saw it earlier in the short video clip: behind us is a year that was historic in many respects. A year in which we had to bear a record loss of 5.5 billion euros. A year in which we lost two-thirds of our revenue and as many as three-quarters of our passengers, and a year in which we had to reduce the size of our workforce by one-fifth. But after this historic and unprecedented year, one thing is also certain: the Lufthansa Group will not only get through this crisis. We are using this crisis to become better. Following the three most successful years in our history, we entered this crisis through no fault of our own. We were stronger than ever, as one of the top five airline groups worldwide, profitable and solidly financed, with successful brands operating out of the economically strongest home markets in Europe and not to mention the best employees in the industry.

  • Return Operation of Moroccans Living Abroad
    Return Operation of Moroccans living abroad Following the High Royal Instructions, Royal Air Maroc is mobilizing to facilitate the routing of the Moroccan diaspora to the country. The company sets up an exceptional and historic device to facilitate the movement of Moroccans living abroad (MRE) during the summer. In this context, more than 3 million seats will be dedicated to this operation between June 15 and September 30, including 600,000 in charters. Summary of MRE operation ticket conditions: Tickets from abroad to Morocco only Date of transport: until September 30 Tickets purchased in cash (no use of previous credit or EMD) Non-refundable, non-exchangeable tickets. For customers who have already purchased their tickets for the period from June 15 to September 30, they can still benefit from the commercial provisions in force: - a refund against a voucher to be used over a later period. These vouchers are valid 12 months, and refundable in cash at the end of their validity; - or a change of travel date, without penalty. Exceptionally, the new date of transport is extended until March 31, 2022 instead of October 31 initially (fare difference may be applied). Customers who have already benefited from a first change free of charge, can exceptionally obtain a second change free of charge on an exceptional basis; - or a cash refund under the fare conditions of the ticket (if the refund is permitted). Passengers who choose one of the above options waive their reservation which will be definitively canceled. Hereafter the updated conditions of travel from/to Morocco following the latest authorities’ decision: The countries are classified into two categories: o The "A" list includes all countries with good indicators concerning the epidemiological situation, in particular the spread of variants of the virus; o The "B" is a restrictive list of all the countries not concerned by the relief measures contained in the "A" list, due to the epidemiological situation.

  • A Study Into the Hub Performance of Emirates, Etihad Airways and Qatar Airways and Their Competitive Position Against the Major European Hubbing Airlines
    A study into the hub performance of Emirates, Etihad Airways and Qatar Airways and their competitive position against the major European hubbing airlines 1.0 Introduction Traffic flows between East and West had traditionally been concentrated at European hubs. Travellers flying Eastbound and Westbound used to connect in airports such as London Heathrow, Paris Charles de Gaulle, Frankfurt or Amsterdam (Dennis, 2007; Bel and Fageda, 2010; Grimme, 2011; Hooper et al., 2011). However, the growth of the Middle East aviation business has led to the rise of new hubs in the region. The Gulf has invested heavily in the aviation business as it is regarded as an important asset for the development of the region, Gulf based airlines are challenging the European network carriers in their long-haul traffic segment. Emirates, Etihad and Qatar Airways, as the most important exponents of the rise of the Gulf, have engineered their bases to become important transfer points for passengers which are beginning to redirect and reshape the traditional traffic flows (O'Connell, 2006; Vespermann et al., 2008; Hooper et al., 2011, Murel and O'Connell, 2011; O'Connell, 2011). The aggressive rise of the Gulf carriers is putting the leadership of the European network carriers and their corresponding hubs under threat (Delfmann et al., 2005). The centre of gravity of international transfer traffic is shifting towards the East, while this displacement is being driven by the Gulf carriers as a result of their effective hub-and-spoke mechanism which is one of the key foundation pillars underpinning their continued success (O'Connell, 2011; Hooper et al., 2011, Murel and O'Connell, 2011).
