Narrative: Approximately one hour from ZZZ on Aircraft X from ZZZ1 to ZZZ we encountered a green system low hydraulic quantity and low pressure ECAM. We performed the action items and turned off the PTU (power transfer unit) and green system engine driven pump. The Captain informed Dispatch; Maintenance; and briefed the lead Flight Attendant. We agreed with the concurrence of Dispatch that the best course of action was to continue to ZZZ. We requested priority handling and received traffic priority to ZZZ. On final approach; we performed the alternate gear extension checklist and landed on the longest runway (XXR). We stopped straight ahead due to no nose wheel steering and waited for the tug to tow us back to the gate. We completed the after landing flows; tow in checklist; and parking checklist back at the gate.The reason for my fatigue call to the Chief Pilot and scheduling following our incident was due to minimal broken sleep from the previous evening at the layover hotel. The hotel was hosting a fraternity convention and my sleep was disrupted from 1-3 am due to the occupants of the room next door. I called the front desk and they notified security to silence the fraternity party. Following the minimal disrupted rest and the stress associated with the hydraulic emergency; I felt I was not fit to continue duty and called in fatigue!


Second narrative: We were approximately 1 hour from ZZZ when we were alerted by a master caution and subsequent ECAM indicating a loss of green system hydraulics both quantity and pressure. I continued flying and had my first officer accomplish the ECAM and subsequently the QRH. We requested priority handling with ATC and I then contacted Dispatch and Maintenance Control; it was decided that given the situation our best option was to continue on to ZZZ. At this point I had our lead flight attendant come up to the flight deck and briefed him on the situation and provided him with the required information. I then made a PA to the passengers explaining the situation and what to expect. We were provided expedited handling by ZZZ ATC and were able to accomplish all remaining clean up items on the QRH in an orderly and efficient manner. A non eventful and smooth landing was performed in ZZZ and we were able to maintain center line where we brought the aircraft to a stop and were meet by CFR and airport operations who towed us back to the gate.


Synopsis: A319 flight crew reported loss of green hydraulic system while in cruise. After communication with dispatch and maintenance; they elected to request priority handling and continue to destination airport.
