What if, and this might be controversial, we went back to the days where we used technology to make life better?

Isn't that the point of it? To allow Delta to fill in the demand curve for a flight more exactly? If they have only 3 or 4 prices (first class, business, economy, maybe a firesale price 24 hours before the flight) they're leaving money on the table. At least some customers are paying less than the demand curve would permit, geometrically.

Of course I'm assuming the AI actually knows the demand curve, and can accurately assess specific customers' utility function.
