From the beginning of the humanity, people have been travelling to different places of the world. These trips are not only for the business but also on the other hand they are for the tours in order to see the different places of the world. Especially in last hundred years, with the rapid development of the technology and more specifically after the using of power of steam in the field of transportation a lot of processes are carried out. 
On this point maybe one of the most important of these processes are the invention of the aircraft. By using the planes people can reach the another places of the world in a short time and easily. After the invention of the aircraft lots of companies are established in order to carry the passengers and get salaries. Especially in last years in world bazaar the salary that are coming from the aircraft transportation is huge extend and on this point because of this reason lots of the airline companies are in competition between us in order to be best. In order to get lots of passengers these companies have to do their advertisements in a good way to the whole world otherwise they can not get much more passengers and as a result of this their salaries can be decrease. On this point in order to increase their quality like in all fields, in airline field, companies decide to create a union. In today’s work we are going to analyze this union that airplane companies are create.
