Secondly, I will talk about the weakness in the airline sector. Chiang Mai is a tourist town the tourists come in large numbers. But Chiang Mai airport is one of the causes may be less tourists. And graphite fly - back to Chiang Mai with a small amount may not be sufficient to meet the needs of consumers. The aviation industry in Thailand has to import from abroad, because without technology. It cannot be produced manually, for example Airways planes from France. Decorate the outside through Physical England and interior Germany and so on. The airline's routes of airlines it is not possible to park or access all the countries around the world, which creates difficulties for consumers that want the aircraft one of the countries before reaching destination. For example, from Thailand to the Florida may have to change planes in Japan before it reaches the destination. All flights of airlines. Inaccessible to all countries, some countries do not support the airport for example, Vatican City, Republic of San Marino and Monaco. Indonesian officials have confirmed that flight Air Asia QZ8501, which disappeared on 28 December, crashed into the Java Sea off Borneo.

As a result, the airline has a lot of long-term liabilities and will even increase because each airline has just the plan to invest, but there are no plans to reduce costs.
