Purpose: The aim of the article is to demonstrate the need for continuous search for new forms of cooperation between carriers and coordination of relations in the process of liberalization and globalization of air transport. In this area of activity, special attention should be paid to the emergence of multilateral alliances, bilateral aviation agreements, and mergers and acquisitions, which are important mechanisms enabling increasing the benefits resulting from the implementation of partnership cooperation. Design/Methodology/Approach: Analysis of integration processes in air transport based on information contained in available literature, which discusses the basic factors of market process regulation that affect the growth of competition intensity in the market. By synthesizing multi-threaded information that provides a basis for drawing conclusions about the processes of aviation market development, it is possible to state the emergence of new trends and conditions within the sector, but also in its broadly understood environment. Findings: The optimal implementation of partnership forms often leads to cooperation between companies from different industries, which results in the joint development and implementation of comprehensive solutions that are beneficial to customers. This also results in an advantage in conditions of growing internal and inter-sector competition.. Practical Implications: The key factor determining competitive advantage in the air transport market is not only price and improved service quality, but also adapting the route network to the needs of passengers. In the case of guides participating in partnerships, unfavourable features of the service are eliminated already in the design phase. This causes a decrease in the outflow of loyal passengers to competitors and an increase in the number of new ones for whom the current conditions are more favourable. Originality/Value: Research into the effectiveness of new forms of cooperation between aviation services market participants brings about beneficial changes throughout the entire passenger service chain, enabling more favourable demand management
