Absolutely correct. That's why I didn't expect Southwest to win this time. Perhaps Southwest far so far ahead the year before that the big dive still left it in first place, or perhaps people unfamiliar with the demise of the online booking bonus voted for Southwest based on outdated information. The primary reason is probably not knowable, but I wouldn't jump to blaming the voting methodology, especially when the margin of random chance exceeds the gap between first and second place.
