I'm flying Montreal to Toulouse next month with a bike (S&S equiped) in a hard case. Can I lock that case or is Canadian (or on the way back, French) security going to want to look inside? Could I use a TSA lock? I have a friend in the US who travels frequently to Europe with his bike and his hard case is almost always opened by TSA in the US so he just leaves it unlocked but I'm not sure what usually happens in Canada. Thanks!
