Zest A320 near Manila on Aug 9th 2014, loss of cabin pressure

An AirAsia Zest Airbus A320-200, registration RP-C8993 performing flight Z2-63 from Jinjang (China) to Manila (Philippines), was enroute near Guangzhou (China) when the right hand bleed air system failed. The crew continued the flight, climbed the aircraft to FL370 but needed to initiate an emergency descent about 250nm short of Manila when the left hand air conditioning system failed, too. The passenger oxygen masks were released during the descent. The aircraft continued to Manila at FL100 for a safe landing about 50 minutes after leaving FL370.
