Loyal QF flyers
Living in NZ and often talking to Australians who visit for work or leisure (and have no interest in aviation), Australians are surprisingly inclined to fly QF (and even Jetstar), even if it involves paying a noticeable premium over NZ where both are flying narrowbodies on the relevant Tasman routes, and the NZ A320 is far newer and can do the route slightly quickly than the Jetconnect 733. I can understand for some with QF lounge access, but for the infrequent travellers their is strong sense of using QF as the default carrier even when they do not have any solid explanation for the decision.
