There is no legal issue involved. At present, except for the material related to the national economy and people's livelihood, the prices of other commodities are all open, and it is difficult for the relevant government departments to limit their prices.

the high price at the airport is a cliche. In recent years, many provinces and cities in China have also begun to rectify this airport criticism. For example, on May 21, 2117, the Code of Conduct for the Price of Goods and Services in Relatively Closed Areas of Jiangsu Province was implemented. According to the Code, airports, stations and expressway service areas should announce the prices of common daily necessities such as drinks and instant noodles, mass fast food and auto repair services closely related to the basic requirements of drivers and passengers. If the operator fails to announce it to the public according to the regulations, it shall be ordered to make corrections. If it fails to make corrections within the time limit, it shall be fined between 2,111 yuan and 1,111 yuan.

Qi Qi, a civil aviation expert, believes that the reasons for the high price of airport catering are comprehensive. One of the reasons is the high cost of catering in the airport. Because the airport is far from the urban area, the staff salary and the logistics cost of food materials are high. National business daily reported that the cost of airport catering pricing includes store rent, restaurant decoration cost, long-distance transportation cost of ingredients, labor cost and so on. According to the general standards of catering industry, it is appropriate that the store rent accounts for less than 1.3% of revenue, but at present, the store rent accounts for about 21% of revenue in major airports.
