民航资源网2019年7月9日消息：民航总局于7月9日（星期二）10点10分03 0 00召开新闻发布会。交通部副部长于瑜在会上指出，与暑假，今年的民航它有以下三个特点：
In the first week, extreme weather is frequent and has a greater impact on flights. According to the forecast, the extreme weather in summer this year has increased compared with previous years, and the risk of flooding is relatively high. Among them, the Yangtze River Basin has more precipitation. More than half of the days in the Pearl River Delta region will be affected by thunderstorms. The thunderstorm weather at Guangzhou Airport is expected to reach more than 40 days. Major routes such as Beijing-Shanghai, Beijing-Guangzhou and Shanghai-Guangzhou will also be affected frequently. In addition, the intensity of the typhoon is strong, and it is expected that 7-8 typhoons will land in China, which will affect the southern coastal airports of the southeastern part of China and the south-central region of China.
Third, the contradiction between supply and demand of transportation capacity exists.
Due to major safety hazards in the Boeing 737MAX8 model, in March, the Civil Aviation Authority issued a notice to domestic companies to suspend the commercial operation of the Boeing 737MAX8 aircraft. According to the requirements, domestic airlines have suspended 97 737MAX8 aircraft and suspended the introduction of the aircraft. Unexpected adjustment of capacity will cause market supply to be affected. Although the airlines can make up for the increase in the utilization rate of existing aircraft, it is expected that in the local market, the contradiction between supply and demand of summer transportation may be more prominent.
Yu Yu said that this year, due to the complicated weather, large passenger flow and more major activities, the pressure on the summer vacation is still relatively large.xx
