How are tickets indicated when the status is blank?

When the status of tickets is indicated as blank, it typically means that the tickets are reserved but the payment has not yet been completed. This status reflects a temporary holding of the ticket reservation for the passenger, allowing them some time to finalize the transaction and make the payment. A blank status does not signify that the tickets have been issued or confirmed, nor does it indicate cancellation or that the tickets have been paid. Thus, 'reserved but unpaid' accurately describes the situation where the reservation exists but the final payment step remains outstanding.
