They're a mixed set of results, to be honest, and partially explain the focus on cost control. However, we have to be close to the stage where we see customer satisfaction and therefore loyalty declining if they push any harder.
However, passenger unit revenue looks like a problem - airlines never generate huge returns and can easily go negative so it's not inherently suggestive of poor management.
Needs to be compared against other airlines' year-on-year - I wonder as well whether the increase in costs is driven by poor punctuality, i.e., it's under-investment that's driving it, rather than overspending.
