Recent changes to the competitive environment in the highly contested Sydney to Los Angeles market have impacted the route profitability of almost 20 carriers. In particular the commencement of non-stop services by Delta Airlines and V Australia has mpacted route profitability of almost 20 carriers. This paper investigates the product factors that enable airlines to command a price premium the Sydney to Los Angeles market. A sample of business and economy class net fare quotes, in addition to data collected on seven product factors is used in this study to estimate the relationship between price and product. The regression results show that service quality, space, connectivity and alliance membership all have a positive influence on price in this particular market. In a practical setting, the research outcomes are particularly relevant to the areas of Airline Pricing & Yield Management, Airline Strategy, Airline Marketing and Product Planning.

Purpose This paper aims to identify drivers of efficiency and their influence on airline performances in South Africa. Unfortunately, the methods currently used to measure airline efficiency fail to address the heterogeneity problem, which blurs inefficiency. Design/methodology/approach To remedy the heterogeneity problem, this paper adopts the meta-frontier framework to identify drivers of efficiency. The interesting feature of the model is that it ensures that heterogeneous airlines are compared based on one homogeneous technology. The model is tested using a panel data sample of nine South African airlines, which operated from 2015 to 2018. Findings The paper demonstrates that structural drivers, namely, “aircraft size”, and “airline ownership” and one executional driver, namely, “the cost structure” significantly influence (p < 0.05) airline efficiency thereby corroborating evidence from some prior studies. Research limitations/implications First, because of the small size of the industry, fewer airlines and a lack of detailed data, the study could not consider other important factors such as optimal routing and network structure. Second, a more rigorous analysis over a period of time would yield better understanding about the growth of the industry in South Africa and recognise the variation in the influence of drivers of efficiency on airline performances over time. Practical implications The results have potential policy implications. First, as the market in South Africa is too small to operate with a smaller aircraft probably, for airlines that operate with smaller aircraft to operate efficiently they should first identify niche markets where they can have a route monopoly. Second, while all state-owned airlines are perfect statehood symbols that define and represent countries, most state carriers in South Africa are highly inefficient. The researcher recommends policymakers to privatise state airlines or seek equity partners. Many nationalised airlines have turned losses to profits in the run-up to privatisation. British Airways, once a large burden on the British taxpayer, is now one of the world’s most efficient airlines. After the privatisation of Air France and Iberia, all two turned from loss-making concerns into profitable airlines. It, therefore, makes no sense for the South African government to expect state carriers to pursue a commercial mandate with such political interference. The very notion of efficiency itself is at risk. Originality/value This paper is a first attempt to identify drivers of operational efficiency using a bootstrapped meta-frontier approach in the airline industry in South Africa. By applying the meta-frontier approach the paper ensures that all heterogeneous airlines are assessed based on their distance from a common and identical frontier.

Modeling airline fares is quite challenging due to the constantly changing fare structure of the airlines in response to competitors, yield management principles, and a variety of political and economic changes, and has become more complex since deregulation. This paper attempts to add to the literature by providing a more in-depth look at fare structure using a multivariate approach. A total 6,200 routes between 80 primary U.S. airports are analyzed using linear and geographically weighted regression models. The results from the global models reinforce some of the expectations mentioned in the literature, while the local models provide an opportunity to analyze the spatial variation of influencing factors and predictability.

Most studies on revenue or yield management have focused on its benefits to airline companies (Anderson & Wilson, 2003; Jerath, Netessine & Veeraraghavan, 2010). Then, the buying behavior of airline passengers has been studied by Diggines (2010), Gupta, Su and Walter (2004) and Yu (2008). General customer search theory has explored the strategies that customers use to make a purchase decision (Stigler, 1961; Koch & Cebula, 2002; Öörni, 2003; Armstrong, Vickers & Zhou 2009). The airline industry has known some difficulties as the overall world economy. Therefore, the challenge of each airline company is to cut costs while increasing profitability and achieving a satisfactory customer service. For this research, the approach is a quantitative one; a stratified random sampling is used and 131 completed questionnaires are collected for the subsequent analysis. The statistical software sphinx IQ is used to analyze the data. Four (4) dimensions of e-service quality are identified, i.e. website ease of use, website design, website reliability and responsiveness. The results show that these four (4) dimensions have an effect on customer satisfaction.

This paper describes an artificial immune system approach (AIS) to modeling time-dependent (dynamic, real time) transportation phenomenon characterized by uncertainty. The basic idea behind this research is to develop the Artificial Immune System, which generates a set of antibodies (decisions, control actions) that altogether can successfully cover a wide range of potential situations. The proposed artificial immune system develops antibodies (the best control strategies) for different antigens (different traffic "scenarios"). This task is performed using some of the optimization or heuristics techniques. Then a set of antibodies is combined to create Artificial Immune System. The developed Artificial Immune transportation systems are able to generalize, adapt, and learn based on new knowledge and new information. Applications of the systems are considered for airline yield management, the stochastic vehicle routing, and real-time traffic control at the isolated intersection. The preliminary research results are very promising.

Purpose The COVID-19 pandemic has triggered a time of crisis and uncertainty for the air transportation industry. The gloomy prospects for the industry have stretched business resilience to a critical point. The crisis has caused damage and shock that the aviation industry has never endured before. This paper aims to provide a comprehensive understanding of both internally and externally generated airline response strategies by examining business practices for crisis management. Design/methodology/approach This study screened research papers and economic reports from authoritative organizations including the International Air Transport Association, International Civil Aviation Organization, World Health Organization and United Nations World Tourism Organization from December 2019 (the month in which the COVID-19 outbreak occurred) to March 2021 (the most recent month at present). The authors also integrated publicly recognized news articles to cover a wide range of business practices in the airline industry. The authors conducted thematic analysis by filtering news articles and economic reports that mentioned the keywords “COVID-19,” “pandemic,” “CoV-2,” “coronavirus” and “corona.” The authors coded the airlines’ response actions along the two-axis matrix (time and magnitude) and generated insights in a timely manner. Findings Major airlines have modified decision-making in relation to the exponential spread of the virus, which is in direct proportion to the deterioration level in the airline industry. When the impact was low in the early stage, major airlines maintained their status quo. Before long, the magnitude of the destruction became high, which made airlines implement capacity adjustments and request government relief measures. As industrial deterioration deepens, airlines keep calling for state aid packages and have changed their focus to the cargo transportation of high-demand commodities and pharmaceutical supplies. Lastly, industrial adversity and uncertainty have made them defer aggressive takeover opportunities. Originality/value Several researchers have investigated the impacts of the COVID-19 on the airline industry. However, there remains a dearth of scholarship on the hampered business activities and crisis management of the airline industry. In the absence of sufficient response strategies against the COVID-19 panic, this paper is to provide a comprehensive understanding of the major airlines’ response strategies to the COVID-19 pandemic. In addition, this paper yields an opportunity for on-site management to review how major global airlines have responded to the crisis and find managerial insights to restore their business sustainability.

Carnival Corporation & plc identified the need for a cutting-edge revenue management system; however, existing solutions from the airline and hospitality industries were not compatible with the idiosyncrasies of the cruise domain. As such, the company partnered with revenue analytics to build a complete revenue and inventory management system to meet its requirements. Yield optimization and demand analytics (YODA) is a system that leverages a unique quadratic programming model to jointly determine cruise prices and allocate cabin inventory to multiple cruises (e.g., 14-day and 7-day lengths) offered simultaneously on a given ship. The optimization inputs come from several machine learning algorithms that predict demand. YODA combines these algorithms with an elasticity model derived from an exponential curve to represent the unique price-sensitivity behavior observed in the cruise industry. The system generates millions of price recommendations each day and has been used to price voyages on 65 Carnival ships, approximately one quarter of the ships in the entire cruise industry, since December 2017. During A/B testing, YODA generated a 1.5%–2.5% incremental uplift in net ticket revenue, which is a significant revenue increase because Carnival was a Fortune 300 company in 2019.

Consumers nowadays frequently make their purchases online. One common pricing strategy on the Internet is demand-based pricing, which allows firms to adapt prices to the demand for their products. This mechanism can undoubtedly be employed more efficiently on the Internet, due to how quickly demand information can be obtained. Within demand-based pricing, one very well-known practice is yield management. This practice was pioneered by airlines, but has spread in recent years to industries such as hotels, rental cars and cruise lines to name but a few industries. The application of yield management was an authentic revolution for the traditional concept of pricing, but has shown that it can be a good strategy when used correctly. Applying yield management requires firms to understand consumer purchasing behavior in order to compare present demand with the demand that is anticipated in the future. Yield management techniques imply the allocation of a fixed capacity to different prices and segments of consumers in order to maximize income. Yield management is sometimes confused with a well-known segmentation strategy called time-based pricing. For this reason, in this paper we highlight the main demand-based pricing strategies that are now being used on the Internet, placing special emphasis on yield management.

This study is aimed at applying yield management to optimize the airlines selling income by determining or allocating the number of passengers in multi-leg flight in which each leg has two fares classes. Basically, yield management is one of allocating and controlling passenger’s seats methods to optimize the airlines income. Normally, the existing yield management model will only consider the fare, demands and capacity variables. Other variables such as operational and distance will not be covered. When those variables are covered, they are considered as constant variables that will not affect the income optimization. The development of yield management model in this study is applying the linear program model approach, in order to obtain an optimum solution in the multi-leg flight. The approach will produce a decision variable; i.e. the number of passengers that will be allocated in each leg for business and economy fares; and objective function; i.e. maximum income and multi-leg flight route being served. The result of the study is a smaller solution, both for the decision variable and objective function. However, the solution is more valid because it considers more aspects, which are ideally more suitable to the actual condition of the flight operational.Penelitian ini bertujuan mengaplikasikan model yield management untuk mengoptimasikan pendapatan penjualan perusahaan penerbangan dengan cara pengalokasian jumlah penumpang pada penerbangan multileg dimana masing-masing leg mempunyai dua jenis kelas tarif. Pada dasarnya, yield management adalah metode pengalokasian dan pengendalian kursi penumpang untuk mengoptimasikan pendapatan perusahaan penerbangan.. Pengembangan model yield management dalam studi ini menggunakan pendekatan model programa linier, untuk mendapatkan solusi optimum dalam penerbangan multileg. Pendekatan ini akan menghasilkan suatu variabel keputusan yaitu jumlah penumpang yang akan dialokasikan pada setiap leg untuk harga tiket bisnis dan ekonomi; dan fungsi tujuannya adalah memaksimumkan pendapatan dan rute penerbangan multileg yang dilayani. Hasil penelitian menunjukkan bahwa solusi yang lebih kecil, baik untuk variabel keputusan maupun untuk fungsi tujuan. Meskipun demikian, solusi ini lebih valid karena mempertimbangkan banyak aspek, dimana idealnya lebih sesuai dengan kondisi aktual dari operasi penerbangan.

Globalization has created immense competitive pressures on corporates. In order to survive and prosper, organizations in the Third World need to redesign themselves for corporate creativity, i.e., for high rates of sustained and successful technological as well as non-technological innovations. This paper provides several examples of how deregulation of the West's airlines industry in the decade of the 1980s stimulated its corporate creativity. It then reviews the literature on the organizational design for corporate creativity to derive a model of the corporate's organizational design requirements for copious and successful innovations. The model proposes that, for superior corporate creativity in a regime of intensifying environmental pressures, the organization needs to choose the following: i) innovation-friendly business strategies; ii) organizational structure; iii) top management style; iv) middle management practices; and v) effective modes of managing innovations. These choices would lead to innovational success, which, in turn, would confer competitive excellence on the organization. This paper reports a test of the model through questionnaire-based data on 65 Indian corporates collected from late 1999 to early 2003. Data were gathered from an average of five top and senior level executives from each corporate on 6-point scales, and each scale was anchored by a statement at each extreme. All the responses from each organization were averaged for each rated scale and converted into a percentage score for the organization. The scales were grouped for aggregation into: i) environmental pressure; ii) innovations-supportive strategic management; iii) innovations-supportive top management style; iv) innovations-supportive organizational structure; v) innovations- supportive managerial practices and culture; vi) effective management of innovations; vii) corporate innovational success; and viii) corporate competitive excellence. The data were secured for the situation ‘now’ and three years earlier and this enabled the computing of changes in each study variable. The data indicated that change in effective mangement of innovations was the strongest predictor of change in innovational success which, in turn, was the greatest predictor of change in competitive corporate excellence. In order to identify the major strategic choices in the face of high versus low environmental pressure, cluster analysis was performed on the data from the 30 highest scoring corporates on environmental pressure and the 30 lowest scoring corporates on environmental pressure. It revealed that, regardless of environmental pressure, organizations that chose to adopt an organizational design compatible with high corporate creativity outscored those organizations that did not choose such a design in terms of both innovational success and competitive excellence. The data also indicated that organizational design for corporate creativity may yield far better performance when change in environmental pressure is modest than when it is large. The reason may lie in differential rates of the diffusion of innovations in high versus low pressure environments. High pressure environments may induce a more rapid diffusion of innovations. The faster the institution-alization of innovations in an industry, the lower, or less durable, may be the competitive advantage conferred on the innovating organization. This paper strongly recommends the following: Managers should redesign their organizations for higher corporate creativity. The core curriculum of MBA programmes needs to incorporate values, competencies, and management concepts that can nurture organizational creativity. Specifically, this paper provides suggestions to practising managers for enhancing corporate creativity which are as follows: Conduct a diagnosis of the design of your organization and identify the items where the gaps with the model are large. Form a cross-functional team to tackle each major gap area. Review the recommendations of the team and identify action points for implementation. Institutionalize a culture of brainstorming for novel and effective solutions and a number of specific innovation-friendly practices.

Abstract As issued in the Competition Policy Brief on the new state aid rules for a competitive aviation industry by the Competition Directorate-General of the European Commission in February 20141, it will be more difficult for unprofitable airports, to obtain financial public subsidies on EU, national or regional level. Although the positive impact of small airports on the regional development and general accessibility was mentioned, still the operating aid to the airports shall be cut out over a maximum of 10 years. It has been further stated that the vast majority of small and regional airports experience problems to cover their running operative costs, as a result from an intensive market competition and overlapping of airports’ catchment areas preventing even some promising airports from growth. Public subsidies are mostly used by the airport management for infrastructural investments, to cover operating losses or to attract price-sensitive airlines. Herewith, among other things, the EU Commission is pointing out at the lack of cooperation structures and network strategies among the regional airports and at rather isolated and individual approach during elaboration of the airport development scenarios. However, the Competition Policy Brief permits public aid to regional airports, among other things if there is sufficient transports need to establish transition periods for small airports; the need for more flexibility of the regional airports in the remote areas has been underlined. The EU Commission is expecting herewith not to close the regional airports, but to stimulate them to operate on cost efficient and profitable basis, and that only the most inefficient airports will be closed. To cope with the upcoming challenges the regional airports are demanded now to revaluate and reconsider their future development plans. While focusing on the passenger traffic many regional airports ignore or underestimate the benefits of the airfreight market. Although the air cargo has rather a low volume, but very high revenue yield part. Business internationalization is one of the important driving forces for the airfreight nowadays as well as decreasing air transport costs due to improving efficiency and growing competition among the air carriers. Most regional airports in the Baltic Sea region that act totally isolated, do not have a clear picture of the current situation on the international air cargo market, its future perspectives and sustainable development plans. Trying to meet the market demand, the regional airports are making huge and unjustified investments, e.g. improving airport infrastructure. It is not clear till now which elements of the Pan-Baltic cargo market could be managed as an alternative revenue yielding services for consolidated operation by air or what infrastructure is needed to provide the opportunity for an optimal economic mix of road-rail-air-sea transport? Nowadays, to a large degree air cargo traffic relies on scheduled, frequent passenger services in hub-and-spoke as well as in point-to-point traffic. Regional airports are presently suffering from a lack of scheduled uplift capacity. The volume currently transported by air in the regional airports is almost entirely based on the occasional charter flights. However, the growth of the air cargo business is likely to be based not only on cargo charters, but to a larger extend on truck-based services for transit shipments. Onward transportation by truck may occur on road feeder service, so called “flying trucks”, where a real truck substitutes a flight. “Flying trucks” are having flight numbers etc., therefore they must be prioritized in many ways in the BSR transport policy. This paper investigates the role of Road Feeder Services concept (thereafter named here as “Flying Truck”) as an optional freight value proposition for the development of the regional airports and their possible participation in the air cargo market as a supplement instrument to generate additional revenue, thus making the airports more profitable and attractive.
