Nowadays, using airplanes as mode of transportation is much more common for most of people, then it was ten years ago. We are traveling for vacations, to work and study in different countries, for business trips. More, and more often, even in Poland, passengers prefer to flight from one city to another instead to take a train. There is nothing surprised in it, especially when we compare the prices. Another nice thing about airplanes is, that you are able to make shopping, in very reasonable prizes, not only on duty free zone, but also on board.
