Politicians fly a lot. So do many of the people they interact with on a daily basis: senior public servants, business leaders, lobbyists and so on. That might help in understanding the mess that is the Australian airline industry.
For most Australians, air travel is an occasional experience. We fly once or twice a year on average. It’s the most affordable and convenient way of covering our long distances but it’s often stressful and not particularly comfortable. For those outside the “Golden Triangle” (Melbourne-Sydney-Brisbane) it can be expensive and the flights we want can be hard to find.
