The "airline industry average"? Sorry, I don't think the airline industry values mile at 2 cents each - the author's off by at least a factor of 10. And it's not an "actual monetary value"; otherwise we'd be able trade them for cash - it's an opportunity cost. And even if the mean FF valuation was 2 cents/mile, I doubt that the median valuation would be that much, which I would believe to be the more important data point for an article like this - if you disagree, please explain why when economists report on the state of the housing industry, they talk about the median price, not the mean.
