Resumen
As a result of the dynamic development of charter flights by air transport there is a need to define and specify factors affecting the decision to make a touristic journey. The charter traffic was analyzed in relation to air carriers and airports. The change of preferences in the choice of final destination during the last 10 years was also indicated. Based on the shown conditions, the main goal and the research hypothesis were defined. The purpose of the article is to analyze the market and determine the factors influencing the development of charter flights in Poland. In this article the research hypothesis that it is a very dynamic market, which depends on many factors, above all on the level of wealth of the society and factors related to safety in holiday resorts was proven. This last aspect has in particular great impact on the offer of charter carriers. Based on the research and analysis carried out (using methods of analysis and logical and statistical constructs) factors shaping demand for tourist services in the air transport segment were determined, and in consequence it leads to the diagnosis of the behavior of charter carriers operating in Poland. Undoubtedly, this issue should be subjected to a thorough analysis in subsequent research works.
