Despite that aviation is global, its detailed specificity in Asia is different than in Europe. The comparison of the aviation market in Asia and Europe allows not only learning differences between the two markets but also shows similarities and opportunities for better regional communication. The work discusses the concepts of transport accessibility, measures of effectiveness and competitiveness of the offer of connections between air carriers and between airports. Moreover work discusses also new orders of planes and new concepts of air connections. The work also touched problem of size of used aircraft, frequency of connections, and the impact of low-cost airlines on the quality and prices of connections on both continents. In this work, we will find out that both markets, although seemingly similar, differ greatly but the main link between them is competitiveness.
