Flying - the dream of human-beings had come true and a lot has changed: starting with planes, which offered minimal passenger capacity to luxurious fares, we have finally arrived at the stage where planes are even used for short distances as means of transportation and where flights can be booked at reasonable fares. The choice of airlines and routes within the EU, affordable fares as well as quality and security standards are more or less the result of an ongoing liberalisation process of this industry, which came into force very late compared to other industries within the EU. For more than a decade the air transport sector has now been part of the Internal Market, which should, according to the EU, one day be seen as "the domestic European market". The book evaluates this liberalisation process and explains where still deficiencies in the Internal air transport Market can be found.
