The PNRCancel transaction is a stateless structured data transaction that supports the cancellation of a PNR (Passenger Name Record). The message deletes all active Itinerary elements.

For some providers in addition to the RecordLocator the specification of further Authentication data is required.

The response to the PNRCancelRQ transaction is the PNRCancelRS message, which contains a Status field, which states, whether the cancellation was successful or not. For some providers a cancellation number or information about cancellation fees can be returned.
