I think it is a poor assumption to think he doesn't. Bigger fleet, more crews and ground handlers, tighter outstation contracts, longer block times. It isn't hard to come up with easy to say ways to improve the OTP. All of these have costs. Rousseau, having come from finance, might be doing a cold hard calculation on the next quarters bottom line of not doing all those things, without a fulsom consideration of long term (and present term international) competitive failings.

Or might know it's both cheaper today to not care, and irrelevant over the long term because the only consumer behaviour that matters is buying or not buying, and the planes are full.
