The Airlines and their staff have been subsidizing travel in Australia for over a decade.
You don't see a train or bus ticket changing prices everyday?
Airlines need to think long term and charge the consumer the real cost of travel. If that affects their cash flow and shrinks the business so be it. The staff that are left will enjoy proper wage increases for inflation and the industry will eventually be stronger. What other industries have the type of cash flow an airline does with the minuscule margins that seem to be the norm?
A ticket should be one price to one location and everyone pays the same rate, obviously the cost of business products etc will be greater.
