They are not based on distance or cost, except in a most general sense. Obviously, if they are losing money on a given route over the long term, and airline may have to raise fares or reduce (or eliminate) service.
That's interesting. I'd still have expected convergence on prices near the flight date, or an undercutting on the shorter more direct leg.
