Low-cost airline Low-cost airline allow us to access a cheaper cross-border travel. In my opinion, though cheap air services are beneficial to our daily life, we still need to restrain our unnecessary travels for the sake of environment problem. People can make visit to various country through the air travel industries. In this case, it can provide them the knowledge of other countries and the opportunity to obtain a job in other countries. Some of those people who work in the other country can access to a better career and have a higher income. In the same way, some business men can find price difference between in the countries when they are in traveling, they can get profit through import or export productions. But if the price of air ticket rise, all of they will lose those chances.
