With the increase of business in the global market and the diversity of employee cultures, there is a need for efficient business communication, in which intercultural sensitivity must be adopted to avoid misinterpretation of messages and misconceptions, in order to competitive advantage in the market. The research established the dimensions by which cultures can be compared (Hofstede G., 2001), and it is these cultural differences that affect communication and understanding among employees, while communication itself is an important factor in the success of the organization. The analysis of the Company's business cases will show the effects of various cultures on communication inside and outside the organization and point out the need to raise awareness of cultural characteristics in order to improve the business process itself. Communication in the Business Aviation Company is an important segment where the regulations of air traffic itself must be understood, as well as the needs of passengers and aircraft owners in order to provide a luxury transport service, which is the core business of the Company. The theoretical presentation of communication explains what communication is and how communication has developed, the ways in which it is communicated in the business world and what influences successful communication. Based on the case analysis on three examples, the paper compared the culture of individual countries and whether employees are "typical examples" of their countries according to theoretical research and how communication recognizes the typical signs of a particular culture. In today's business, especially in the aviation industry, given the daily international flights, it is important to determine the skills that a global manager must have, and in order to do business successfully and maintain successful communication with employees of different cultures. Analyzing the communication in the presented examples, we come to the conclusion that many employees are not aware of cultural differences in the organization and often come into conflict because of the expectation of the flow of communication to take place in their own culture. Based on this paper, needs of employee education are pointed out in order to increase awareness of the cultural differences that are present in the everyday business environment.
