In recent years, it has been observed that there is a very intense and fierce competition among airline companies in the airline industry all over the world. It is a fact that the importance of financial management, which is mostly based on reducing expenses and increasing revenues, in addition to other multidimensional issues, has increased tremendously for these companies in order to maintain their activity and sustainability. Airlines have had to look for ways to reduce their overall costs and increase their profitability. In addition, the Corona period we have been going through, as a force major negative factor, has further increased the importance of this search for companies. In the civil aviation industry, continuity of airworthiness and maintenance costs constitute a large portion of total airline expenses. In this study, the effect of proactive aircraft maintenance scheduling on the maintenance costs and airline profitability is examined. In the study, Turkish Airlines (THY) was chosen as the company that was handled. The fact that the company has a separate special maintenance and repair group (Turkish Technic) was effective in the selection of this company. In addition, some additional qualifications (very rooted, with corporate governance, Turkey's top largest airline, full service carrier airline, member of IATA and the global airline confederation-Star Alliance, and a publicly traded/listed company (Borsa Istanbul-BIST) were also among other factors in selection of the company. Methodologically, the survey method was used to collect the data. The survey was performed on 150 Turkish Technic personnel who actively/directly take place in aircraft maintenance and scheduling such as aircraft maintenance technicians, maintenance planning clerks/experts, supervisors, chiefs and managers. The SPSS-22 version was used to analyze the data, including the necessary tests. It was concluded that there is a strong correlation between maintenance scheduling and the maintenance costs. The study revealed that a proper maintenance planning greatly affects maintenance costs. It is also found that a proactive approach to the maintenance scheduling and planning has a positive effect on decreasing the maintenance costs. Furthermore, the study indicated that aircraft maintenance scheduling affects airline profitability in a positive way as well.
