One of Air Canada’s longest flights landed a lot earlier than expected after the plane was diverted due to a strange smell being detected on board.

Flight AC40 was due to take off from Auckland, New Zealand at 2pm local time on Tuesday, 13 January for a 12 and a half hour flight to Vancouver, Canada, one of Air Canada’s longest routes.
