If the airplane tikets are as cheap as bus tickets , I will travel around world 3 times! Nowadays,the air travel is getting cheaper in order to attract more customers. People have different views about the increase of cheap air travel. Some people believe that the increasingly number of cheap air travel has brought a wide range of benefits. Firstly, the more cheap aire travel will improve the effciency of the public transport. China, as a country with a large population, always suffers a heavy depressure of traffic at every public holiday. Especially at the spring festival, the trains as the first choice for the long-term travel is always inadequate of the people. If there are more cheap airplane tickets can be provided, the more people will prefer to use this fast and economical way to travel, which enables the public transport to be more efficient. Besides that, the cheap air travel provides equal opportunities to broaden their horizons for all the people. It means that both the wealthiness and the people from low-income families can afford the fees of air travel, so that they can go around world and experience different culture and life styles. For instance, teenagers can take part in some training course or campus overseas with lower costs. The others think the development of cheap air travel has drawbacks of environment and resources. Since the cheap air travel becomes more popular, there will be more aircrafts in the sky. And they demand more resources and cause air pollution at the same time. But I believe those situations will be changed by science development and new technology in the future. In conclusion, although it will affect the environment, I believe that the development of cheap air travel brings various benefits for our life.
