Hello
as far as i know this route is only for summer time , and they started it last year =

if your booking is during winter , probably its a codeshare and maybe with a layover somewhere ,so you need to check the details
In case your flight is cancelled , AF will contact you with two offers = either refund your money or rebook you on another airline under the same conditions
