Aircraft
We leveled off at our final cruising altitude of FL350. All systems were set up in their normal configurations. About ten minutes into cruise flight the cabin altitude warning horn went off. We immediately started memory items for the situation. By the time I had my O2 mask on and checked the cabin altimeter; we realized the cabin had already gone up to 14;000 - 15;000 FT. We contacted ATC; declared an emergency; and asked for an immediate descent and continued with the QRC/QRH procedures. During the descent with the outflow valve fully closed; the aircraft still lost pressure. We notified the flight attendants about the issue and made an announcement to the passengers. When we leveled off at a safe altitude; I decided to continue on to [destination] because we were fairly close and had enough fuel at that time to make it there. We landed without further incident.
[Narrative 2 had no additional information.]
B737-300 flight crew reported loss of cabin pressure in cruise flight at FL350. They declared an emergency; executed an emergency descent; and continued to their nearby destination.
