Not uncommon for airlines to ensure this.

My friend was denied boarding by SQ for not having the credit card she had present with her that was used to book the ticket. This was a few years ago. And the credit card was under her name.

CX also enforces this, and once I was told the alternative was for credit card holder to visit the local office before traveling so that the staff can verify the payment.

However for online bookings that use the SMS verification it is not needed anymore (was told by the CX agent on the phone).
