Narrative:

Approximately 4 hours into the flight I started to notice an odor of burning. I thought it was coming from the air conditioning system. Immediately; I turned off the power port buttons on the fwd jumpseat panel (another flight attendant turned off the chiller system in the mid galley). I went to the captain who was on rest break. He began the process of troubleshooting. The odor seemed to begin mid aircraft and floated to the fwd cabin. It stayed pretty much the entire flight; very strong in the beginning and then lessened only to intensify on landing. Passenger were very much alarmed; the flight attendants did as much as they could to assure them that the captain was aware of the situation and working to clear the air. One of my passenger was very upset; and on landing; one of the coach passenger yelled as she was leaving that we had jeopardized her life. Flight attendants complained of headaches and affected sinuses.callback conversation with reporter revealed the following information: the reporter flew several trips with the same crew after this incident and states that the captain gave her a copy of the report that he filed with the company. The report indicates that the crew consulted with maintenance and continued the flight after turning off the affected oven; securing the left pack; and the trim air system. The aircraft apparently had a history of problems with this oven; and had just come out of scheduled maintenance without an intervening flight.

IMMEDIATELY; I TURNED OFF THE POWER PORT BUTTONS ON THE FWD JUMPSEAT PANEL (ANOTHER FLT ATTENDANT TURNED OFF THE CHILLER SYSTEM IN THE MID GALLEY). I WENT TO THE CAPT WHO WAS ON REST BREAK. HE BEGAN THE PROCESS OF TROUBLESHOOTING. THE ODOR SEEMED TO BEGIN MID ACFT AND FLOATED TO THE FWD CABIN. IT STAYED PRETTY MUCH THE ENTIRE FLT; VERY STRONG IN THE BEGINNING AND THEN LESSENED ONLY TO INTENSIFY ON LNDG. PAX WERE VERY MUCH ALARMED; THE FLT ATTENDANTS DID AS MUCH AS THEY COULD TO ASSURE THEM THAT THE CAPT WAS AWARE OF THE SITUATION AND WORKING TO CLR THE AIR. ONE OF MY PAX WAS VERY UPSET; AND ON LNDG; ONE OF THE COACH PAX YELLED AS SHE WAS LEAVING THAT WE HAD JEOPARDIZED HER LIFE. FLT ATTENDANTS COMPLAINED OF HEADACHES AND AFFECTED SINUSES.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR FLEW SEVERAL TRIPS WITH THE SAME CREW AFTER THIS INCIDENT AND STATES THAT THE CAPT GAVE HER A COPY OF THE RPT THAT HE FILED WITH THE COMPANY. THE RPT INDICATES THAT THE CREW CONSULTED WITH MAINT AND CONTINUED THE FLT AFTER TURNING OFF THE AFFECTED OVEN; SECURING THE LEFT PACK; AND THE TRIM AIR SYSTEM.
