Yayın Examining the impact of economy class flight satisfaction on brand loyalty in the light of falling aviation profitability after COVID-19: Case of Turkish Airlines(EBES Yayınları, 2023) Kartoğlu, Ömer; Aksoy, Tamer; Yönetim Bilimleri Fakültesi, İşletme BölümüThe aim of this study is to evaluate whether customer satisfaction for the most preferred economy class flight in airline businesses has a positive effect on brand loyalty. Turkish Airlines was chosen as the company that was discussed in the study. In the study, it was also aimed to investigate whether the perception of the effect of customer satisfaction on brand loyalty differs according to demographic characteristics. The study is also important because it provides up-to-date information about customer expectations that make the company preferable after the decline in airline profit rates after Covid-19. The first main hypothesis was created to measure whether customer satisfaction with economy class flight has a positive effect on brand loyalty. The second main hypothesis of the study was created to measure whether the perception of the effect of customer satisfaction on brand loyalty differs according to demographic characteristics. Questionnaire method was used methodologically in the collection of research data. 330 personnel responded to the questionnaire prepared according to a 5-point Likert scale. The SPSS-22 version was used in the analysis of the data, which includes the necessary complementary statistics and tests (frequency, percentage, mean, standard deviation, Cronbach's Alpha, factor analysis, correlation analysis, regression test, t-test, analysis of variance, Post-Hoc test, etc.). In the study, it was concluded that there is a positive and significant relationship between economy class customer satisfaction and brand loyalty. In addition, it was revealed that there were statistically significant differences between the groups according to gender, job position and educational status, but there was no significant difference according to age and travel purpose.Yayın The impact of cargo and ancillary revenues on net profit for full service carrier airlines(EBES Publications, 2021) Aksoy, Tamer; Baş, Onur; Yönetim Bilimleri Fakültesi, İşletme BölümüAirline companies have had to manage their capacities better and generate new revenues due to low profitability rates, high risk and increasing competition conditions. As a result of the sale of products and services offered free of charge to passengers by companies applying the traditional airline business model for a separate fee to increase the revenues of the companies applying the low cost / low cost airline business model, ancillary revenues (AR) have occurred. AR are what airline companies offer to their passengers other than the tickets they have sold, services such as inflight catering, baggage fees, loyalty programs, seat fees, advertising and commission revenues and in-flight entertainment systems. In this context, in order for airline companies to survive today in tight competition conditions, it is important that they gain AR in addition to their main income. The study examines the effects of cargo revenues (CR) and AR on net income (NETINCOME) for three full service carrier airline companies:Turkish Airlines- THY, American Airlines-AA and Delta Air-DA. As far as it is known, there is no direct empirical study that addresses the effects of CR and AR on NETINCOME for airlines companies. The data used for the period of 2014Q1-2019Q4 was collected from Sorensen&Lucas (2020), IATA and related airline companies’ annual reports in their official websites. Methodologically, a logarithmic econometric model was used in which CR and AR were included as independent variables and NETINCOME as dependent variable. SPSS-22 version was used to analyse data to cover the necessary analysis and tests (regression, reliability, cross section dependent, second generation unit root, delta slope homogeneity, cointegration, casualty etc). The study indicated a positive correlation existed between CR and AR and NETINCOME. The increase in CR and AR also increase the NETINCOME of airline companies. It was revealed that the AR in aviation, provide an important resource for airline companies. The study also reflected that AA and DA are among the top three companies with the highest AR in the world, while THY-AR are lower compared to these two US companies. On the other hand, the study indicated that the contribution of THY-CR revenues to NETINCOME is much higher than the other two companies. The results are also compatible with IATA data that THY is among the top 10 carrier companies worldwide in terms of CR. It is recommended airline companies should give enough importance to CR and AR to increase the profitability.Yayın Examining the impact of cargo and ancillary revenues on net profit for full service carrier airlines(Busssecon International, 2022) Aksoy, Tamer; Baş, Onur; Yönetim Bilimleri Fakültesi, İşletme BölümüIn this study, the relationships between cargo revenues, ancillary revenues and net profitability of airline companies were examined in the examples of three full-service airline companies (Turkish Airlines, American Airlines, Delta Air Lines). Methodologically, a logarithmic econometric model was used in which cargo revenues and ancillary revenues were included as independent variables and net profit as dependent variable. The data used for the period 2014Q1-2019Q4 were collected from the annual reports on the official websites of related airline companies and The International Air Transport Association (IATA) and Sorensen&Lucas (2020). EViews 10 and STATA-15 versions, which are the most modern econometric analysis programs that can be used to control the stationarity, were used in the analysis of the data. In addition to econometric analyzes and general statistics, Cross Section dependency tests, CADF second generation unit root tests, Delta slope homogeneity tests, Panel cointegration analysis, Westerlund Panel cointegration tests and Dumitrescu Hurlin Panel Causality tests and Breusch Pagan LM Tests were also performed. The study revealed that there is a cointegration between cargo revenues, ancillary revenues and net profit, and there are a one-way causality relationships from both cargo revenues to net profit and from ancillary revenues to net profit. The study also indicated a positive correlation between cargo revenues and ancillary revenues and net profit. In other words, cargo revenues and ancillary revenues have a positive effect on net profit of airline companies. In addition, the study found that aviation ancillary revenues provide an important resource for airline companies; furthermore, two US companies are among the top three companies with the highest revenues in the world in terms of cargo and ancillary revenues; also showed that Turkish Airlines' ancillary revenues are lower than those of these two US companies. On the other hand, the study showed that the contribution of Turkish Airlines cargo revenues to net profit is much higher than the other two companies. The results are also in line with the IATA data, where Turkish airlines are among the top 10 carrier companies worldwide in terms of cargo revenues. In the study, it is also suggested that airline companies should give more importance to cargo revenues and ancillary revenues in order to increase their profitability.
