Narrative:
Jfk responded to my write-up of a fault light on left pack with a placard for left pack. After leveloff at FL290, after about 1/2 hour at cruise, ECAM warned of excess cabin altitude. Both outflow valves were closed and the cabin was about 9500 ft. I descended to 18000 ft, declared an emergency and conversed with dispatch as to continuing at 18000 ft to san juan. Dispatch suggested returning to jfk, but we talked more and I felt safe with a block altitude clearance to 25000 ft. We maintained between 25000 ft and 24000 ft and continued to san juan. On approach, the flight attendants advised of a smell of something burning, so I asked for emergency equipment. It seems to me that dispatch with a pack inoperative should call for an inspection of the other pack before releasing for flight.

Title: A300 FLT CREW HAS CABIN PRESSURIZATION MALFUNCTION. DECLARES AN EMER AND DSNDS TO A LOWER ALT ENRTE TO SJU.
Narrative: JFK RESPONDED TO MY WRITE-UP OF A FAULT LIGHT ON L PACK WITH A PLACARD FOR L PACK. AFTER LEVELOFF AT FL290, AFTER ABOUT 1/2 HR AT CRUISE, ECAM WARNED OF EXCESS CABIN ALT. BOTH OUTFLOW VALVES WERE CLOSED AND THE CABIN WAS ABOUT 9500 FT. I DSNDED TO 18000 FT, DECLARED AN EMER AND CONVERSED WITH DISPATCH AS TO CONTINUING AT 18000 FT TO SAN JUAN. DISPATCH SUGGESTED RETURNING TO JFK, BUT WE TALKED MORE AND I FELT SAFE WITH A BLOCK ALT CLRNC TO 25000 FT. WE MAINTAINED BTWN 25000 FT AND 24000 FT AND CONTINUED TO SAN JUAN. ON APCH, THE FLT ATTENDANTS ADVISED OF A SMELL OF SOMETHING BURNING, SO I ASKED FOR EMER EQUIP. IT SEEMS TO ME THAT DISPATCH WITH A PACK INOP SHOULD CALL FOR AN INSPECTION OF THE OTHER PACK BEFORE RELEASING FOR FLT.
