Can I buy a plane with an punctuality rate of 80?

Yes Punctuality rate refers to the proportion of flights with planned departure time (that is, normal flights) to the total number of flights when the air passenger transport department executes the transportation plan. Official website shows that the punctuality rate of one of the top ten domestic airlines is above 70%, so planes with punctuality rate of 80% can be bought. The punctuality rates of Shenzhen Airlines, Xiamen Airlines, Shanghai Airlines, Shandong Airlines and Hainan Airlines are all below the average level of 80%.
