It was the BA9 enroute to SYD from BKK; the BA12 SIN-SYD is operated by a 777 at the moment.
Apparently it was smoke on the flight deck, from the Capts air vent.
Could not have been much fun diverting to DPS (Bali) at night wearing O2 masks.
Engineers are still scratching their heads. Have to dismantle the LH side of the flight deck to get access to check for source.
All the pax delivered safely to SYD today on another BA744…… I will be home 5 days late though!!
