Narrative:

Loss of yellow hydraulic system due fluid leak. We had a normal preflight. First officer did not notice any hydraulic leaks on walk around and all fluid levels checked on system pages. We had a normal taxi out; take off and climb out. In cruise; I checked system pages and noticed green system level below green band but well above amber band. Blue system was in green band. Yellow system was below green band and just above amber band. We continued to monitor yellow system level. About 1 1/2 hours out we got a caution and ECAM for hyd low pressure. We followed ECAM; turning off yellow engine pump; ptu; and applying landing distance procedure. We followed up in QRH for further guidance. There was no 'land as soon as possible' so I continued. I informed dispatch of the failure; my intentions; and asked them to coordinate with [maintenance and operations]. I also informed them of my intentions and request priority handling to a long runway. We had lost nose wheel steering; number 2 reverser; spoilers 2 and 4; and other goodies; so I felt it prudent to request a long final and emergency equipment to standby. We had slow flaps and slats so I wanted to be configured and on speed early. I landed from the ILS. At touch down I used rudder; differential braking with normal brakes; and idle reverse on engine 1. I was able to get a/c stopped and maintain directional control with about 4000 ft remaining while not making any aggressive control inputs. I held the aircraft with toe brakes even though we had accumulator pressure. Fire and rescue inspected the aircraft and found nothing. I shut down engine 2; left engine 1 running for green hyd pressure. Tug hooked up and towed us to gate. I shut down when chocks were in place; secured the aircraft; wrote up the discrepancy and notified [maintenance]. No deviations from far or company regs were required.
