Company Policy; Procedure; Environment - Non Weather Related
During briefing; the Captain informed me that the Sabre Flight Planning system did not calculate the required fuel correctly for the ETOPS airport. Fuel required was showing 49;064 LBS in the ETOPS page. On the flight plan; the ETOPS fuel showing was 47;719 LBS on release number 2. I amended to release 3 prior to departure to add fuel for the three alternate solution.
Dispatcher reports being informed by the Captain involved that the Sabre Flight plan has an error in the ETOPS fuel required.
