I've been looking in to this recently and the point he makes about flying crazy routes to get extra miles is a little off. It may work for some airlines, but I know for others you earn miles for how far your start and end points are apart from each other, not how long your route actually was. So if you're flying Los Angeles to Seattle, but have a layover in Miami, you would only earn the miles that someone flying Los Angeles to Seattle would.
