As far as I know, Ping An Pratt & Whitney payment will not directly affect the credit card limit after 90 days overdue. Ping An Pratt & Whitney is a loan company. When the borrower is 90 days overdue, Ping An Pratt & Whitney can take compensatory measures, that is, transfer the overdue creditor's rights to other institutions through the transfer of non-performing creditor's rights. This has a certain negative impact on the borrower's credit record, which may reduce its credit score and credit rating.

However, credit cards and loans from loan companies are usually independent, that is, the credit limit of credit cards is usually determined according to the cardholder's personal credit status and repayment ability. Therefore, loans overdue will not directly affect the credit card limit. However, the overall credit status of the borrower may be affected, thus affecting the possibility of applying for a credit card line in the future.

It should be noted that the specific situation may vary according to the policies of banks or financial institutions. I suggest you consult the relevant credit card issuing banks or financial institutions to obtain accurate and detailed information.
