They are fixed and sunk *in the short term*. In the long term, all costs are flexible. It costs money to build the next version of an IT system. It costs money to buy the next plane. It costs money to rent and outfit a particularly sized lounge.
Correct, and it's an aspect of the equation I've deliberately ignored because I didn't want to lengthen my already lengthy posts.
The long-term malleability of even short-term fixed costs is why, for instance, it's not a good idea to give
all your customers lounge access for instance. But as long as there is spare capacity (and I acknowledge there've been complaints about overcrowding in the lounges) it's preferable to sweat those assets over a larger customer base because of the incremental cost/incremental revenue equation that comes into play in the short-medium term.
The example I've used elsewhere is priority boarding at the first-class check-in counters. Restricting these counters
only to first class passengers would be counter-productive (no pun intended) as the FF&E and people staffing those counters would be underutilised. Opening them up to Platinum members flying Economy helps work those assets more efficiently (and reduces the need to buy non-first class counters, thereby saving Qantas money). Opening them up to everyone on the other hand would defeat the point of premium product/service differentiation altogether.
All this banging on about how profitable these fares are flies directly in the face of what the people actually providing the service are saying. [...] Yet, somehow, without access to the actual books, any statistical data, or even any experience running an airline, this forum's in a position to state that QF's cutting off a profitable venture? Surely the reverse conclusion - that you're wrong - is far more likely?
The people providing the service are no doubt better informed of the facts and figures than 99.99% of the people reading these forums, including myself. (Or at least some are. For instance, I doubt that the person drafting the media release had a comprehensive accounting understanding of Qantas's financial situation. They might have just been told "the reason for cutting the MASAs is that they're losing money, so say that.")
But it doesn't mean that they don't represent and spin these facts and figures in their favour. (The old "Lies, damned lies and spreadsheets" argument.) And it certainly doesn't mean they always make the right strategic decisions in response to these facts and figures. So for instance, it's very easy for something that was seen as an investment by one regime to be seen as a cost by another. The truth isn't always easy to discern.
