If there is an overdue situation in China’s credit record, it will have a negative impact on an individual’s credit status, which may result in being unable to fly. Specifically, there is no clear time limit for how long you can't fly overdue, because it depends on the regulations of each airline and the relevant regulatory requirements of government departments.

First of all, airlines will inquire about passengers’ credit status when purchasing tickets and checking in. If there are serious overdue circumstances in the credit report, the airline may refuse the passenger to fly. This is to ensure the safety of flights and the rights and interests of passengers.

Secondly, how long the overdue period will affect whether you can fly is also related to the specific overdue behavior. Generally speaking, minor overdue situations may not cause significant restrictions on passengers' right to fly, but if the overdue situation is serious and lasts for a long time, airlines may take restrictive measures.

In addition, the supervision of personal credit status by Chinese government departments will also have an impact on flying. According to relevant policies and regulations in my country, if an individual's credit status is poor, he may be restricted from flying or other means of transportation.

In short, there are no clear regulations on how long the credit limit must be overdue to allow you to fly. Instead, it is decided by airlines and government departments based on the individual's credit status and the severity of the situation.

Extended information: China’s personal credit reporting system is led by the People’s Bank of China and aims to record an individual’s credit status. Overdue means that a person fails to perform the agreed payment obligations on time. The specific period is stipulated in the loan contract and other documents. Overdue credit reports will have a negative impact on financial services such as applying for loans, applying for credit cards, and purchasing insurance. In addition, China has also implemented a social credit system that combines personal credit information with other aspects of credit performance for credit evaluation in various fields. This comprehensive credit assessment may also affect an individual's right to fly. Therefore, it is necessary for individuals to maintain a good credit status and avoid overdue payments.
