Where do you get this nonscence from? The airservice to OLD and PMH by Alliance is not a Qantaslink service. They are contractors to BHP Billiton around OZ to supply fly in fly out services to their operations. Alliance has also the contract for PMH with Oxiana. The reason they fly to OLD with a Qantas flight number is due to a deal they struck with Qantas to allow the non BHP employees in the town of Roxby Downs ie medical staff, teachers,shop owners etc to use the service and able to book via internet or travel agents etc since Rex pulled out. I guess it is good for Qantas too for onward traffic. The above does not apply for the PMH service as that has no town. That is also why Alliance aircraft are not painted with the red tail like National Jet.
