I'm not sure this is what happened in this case, but having your own following in a particular niche does have its perks. If your following is large enough, you get invited to all kinds of events for free. You usually receive the best service and the best discounts. Sometimes, some sponsors will even pay you to disseminate promotional materials on their behalf.
If that idea doesn't entice you, the next option is to visit a country that had a recent terrorist attack. I am actually very serious about this. Tourists are easily spooked. But if you keep yourself informed of current events, figure out where the specific areas you need to stay away from, and speak to the locals (not just in the travel industry and therefore not with an incentive to lie to you) wherever you go to ask about what's safe and what's not, you can get yourself some very cheap flights and still be relatively safe. And you'd actually be helping with their local economy during a time of hardship.
And yes, those flights will most likely be empty on the way there. But unfortunately, there is no guarantee that the flights coming back won't be filled up to capacity, or to near capacity.
