On the Airbus, if a landing elevation is set (either manually or through the Flight Management Guidance System) that is higher than the cruise cabin altitude then the cabin altitude will increase to the higher of either the cabin altitude, or landing elevation-6000 feet.
The cabin altitude is limited to 7,350' on flights more than two and half hours or 8000' on shorter flights. In the La Paz example 13,600 feet, the cabin would be at either 7,600' feet (13,600'-6000')or 8,000' if a short flight. On descent the cabin altitude would then climb to achieve landing field pressure + 0.1 psi just prior to landing. 80 seconds after landing the outflow valves are controlled fully open to remove any residual pressure.
Incidentally,on the A330 and A340 max runway altitude for takeoff and landing is 12,500'.
