Money can't buy happiness, and as it turns out -- it can't really buy legroom either. In a recent article from the Harvard Business Review, our favorite brainiacs conclude that on a plane, "there’s no correlation between price and comfort, including legroom." Total. Bummer. After surveying roundtrip airfares, the authors noted that people paying less sometimes got more legroom than those paying more, with a difference of a few inches of seat pitch.
