Unfortunately people guard this stuff closely for fear of airlines catching on, or at least they used to. I haven’t looked at it seriously in a couple of years but airlines were making a real effort to tighten up fare rules to cut down on this. Even when I was doing it a lot, all of the easy stuff was already mostly fixed, save for the odd mistake here or there. I for instance would never post the hacks I’ve discovered, and would only share them with a select few. It’s self preservation, but once they’re known, travel bloggers spread them and every Karen ends up doing it.
