An Air France Airbus A380-800, registration F-HPJC performing flight AF-346 from Paris Charles de Gaulle (France) to Montreal,QC (Canada), was enroute at FL380 over the Atlantic Ocean about 75 minutes into the Atlantic crossing, about 600nm west of Ireland, when the crew declared PAN due to smoke in the cabin, turned around, descended to FL370 and while initially heading towards Ireland decided to return to Paris Charles de Gaulle where the aircraft landed safely on Charles de Gaulle Airport's runway 26R about 2.5 hours after turning around.
The flight was postponed to depart the following day noon as flight AF-4094 with a delay of 20 hours.
