In terms of business economics including airlines, revenue is irrelevant except for determining the percentage of revenue that profit constitutes. If an organization is generating anything approaching 10% of revenue in profit it is doing well and doesn't need to keep increasing every year as 10% equals sustainability in the long term.
People need to realise that revenue is just the money that's coming in the door, it is too often used to talk about how profitable a company is but revenue is simply one component in determining the success of a company - e.g. revenue minus cost = profit.
In terms of that, Qantas is consistently one of the most profitable airlines in the world and I don't include the 2.6bn loss as it wasn't a loss at all but a write down and I'm not convinced it wasn't a case of creative accounting to use as rhetoric to get a better deal out of the government and/or to leverage other benefits such as tax minimization for a number of years afterward.
