Air Fares 101 – Why do fares change all the time? 12 years ago
Or, create a system where the airline benefits from you gaming the system.
For example, imagine you 'game' the system in such a way that you will definitely be in an otherwise-empty seat, and you would only buy a ticket if you successfully got your intended discount. Then, airlines wouldn't be incentivized to 'adjust' and you could keep getting discounts.
We are playing with a few prototypes to do exactly this at http://www.projectcaspini.com. Sign up for the mailing list if you are interested.
