A British Airways Boeing 747-400, registration G-CIVJ performing flight BA-293 from London Heathrow,EN (UK) to Washington Dulles,DC (USA), was enroute at FL340 about 100nm northwest of Shannon (Ireland) when the crew declared PAN PAN reported they had a burning smell in the cabin and were unable to locate the source of the smell. The crew requested to return to London. ATC offered a diversion to Shannon, the crew maintained however to return to London. The aircraft turned around and maintained FL340 for the return. The aircraft landed safely back in London about one hour after the decision to return.

A passenger reported a burning odour developed in the aft cabin near the aft doors. Cabin crew thought the odour originated from some of the ovens and shut the galley down, the odour however continued. The captain came back to the aft cabin and returned to the cockpit, then announced the aircraft was returning to London. The flight attendants were commenting to themselves about feeling dizzy and suffering from headache.

The flight was cancelled.
