The aim of this study is to examine the variation of the activities of airlines over the years and to identify the factors that determine this activity. In this context, 45 airlines operating in different regions of the world and providing continuity of data for the period 2010-2016 have been studied as empirical. In the study, the variation of the activities of airline companies according to the years, data coverage analysis was studied. The factors determining the effectiveness were studied through the Tobit regression method. The findings of the study show that the fourteen airlines involved in the analysis were effective in the relevant period and performed better than the other airlines. The 10 airlines have not been active in all of the periods. The results of Tobit analysis show that the positive increase in the total number of passengers moving, the availability rate and the total income variables increased the efficiency level.

The aim of this study is to examine the yearly changes in the efficiency of airlines and to reveal the factors that determine this efficiency. In this context, 45 airlines operating in different regions of the World, with data for 2010-2016 period, have been examined empirically. The change in the efficiency of airlines over the years was explored using data envelopment analysis (VZA). The factors determining the efficiency were examined through the Tobit regression method.  Findings of the study Show that the fourteen airlines involved in the analysis are efficient in the period concerned and have a better performance than other airlines. Ten airlines were not efficient in all of the related periods. Tobit analysis results show that the positive increase in the number of total passengers carried, load factors and total income variables increases the efficiency level.
