A British Airways Boeing 787-10, registration G-ZBLG performing flight BA-238 from Boston,MA (USA) to London Heathrow,EN (UK) with 106 people on board, was enroute at FL410 over the Atlantic Ocean about 650nm northeast of St. John’s,NL (Canada) when the crew reported smoke in the cabin and decided to turn around and divert to St. John’s. The aircraft landed safely on St. John’s runway 29 about 110 minutes later.

The Canadian TSB reported an acrid smell was detected at seat 12A, however, no source was found. 2 cabin crew were taken to a local medical facility for assessment due to inhalation of fumes and subsequently released. Maintenance inspected the aircraft and found no trace of fire or heat. Multiple passenger service units and ceiling panels were removed in the area around seat 12A with no findings. “Maintenance also carried out seat inspections as well as air conditioning pack, galley equipment, in-flight entertainment, and auxiliary heater operational checks with no faults noted. The aircraft has been returned to service.”
