Abstract
From Icarus to Airbus 380, the dream of the "flying man" seems to be universal. During the 20th century this dream was becoming real through the development of the plane and airline companies which manage it. The rising need to travel has obliged the authorities to regulate this market by rules and agreements. The last trend is the "open skies" agreements which deregulate between two countries some of commercial, logistic, strategic and economic points of airline company organization. In 2005, a major "open skies" agreement about Trans-Atlantic aviation has been signed with difficulty by EU and US. By focusing on business issues, my study deals with the change this agreement will bring for airline companies, according to the key question of the case study: "What strategies might airlines adopt in this new regulatory environment?" As an answer, I have decided to divide the study in three parts.
