Narrative:

About 2 1/2 hours after takeoff from lgb, a flight attendant noticed a sulfur-like smell coming from the front of the coach cabin around the 2L and 2R areas. The smell was a burning, electrical smell which became stronger near the ceiling of the aircraft. Several passenger also noticed the smell. The captain flushed the cabin by raising the cabin altitude to 10000 ft. The smell then moved to the middle of the airplane. A couple of the flight attendants working in the main cabin tried to locate the source of the smell, but could not. We advised the captain of the burning smell, and he decided to land. No passenger were injured, ill, or harmed during the emergency landing. After we arrived in den, the passenger were asked to leave their carry-on items/luggage on board. The women were allowed to take their purses. After the passenger and crew deplaned (via jetbridge) maintenance came aboard the aircraft, but were not able to find anything wrong or unusual about the airplane. No evacuate/evacuation was necessary.
