Hence, as it has already been analyzed above, tourism sphere has a considerable progress potential. However, this potential is not something that corporations in this topic waste. In addition, compared with recent decade they have increased their efforts a lot (especially in the field of airplane travelling) to make more and more people be keen on their services. For example, about ten years ago it was for majority of people not possible to imagine that it would be possible to travel with an airplane for funds that would be the same as some bus connections in their country! Consequently, in recent years we may recognize a huge boom in the field of airplane travelling, which is relatively reasonable despite the fact that there are still accidents happening, in which a variety of people were killed.
