On October 4 Flintshire made his third bid for the Prix de l'Arc de Triomphe and started at odds of 18.6/1 in a seventeen-runner field. He was among the leaders from the start and stayed on strongly in the straight to finish second, two lengths behind the winner Golden Horn. Flintshire attempted to repeat his 2014 success in the Hong Kong Vase and finished second to the Irish three-year-old Highland Reel.
