Silly question...but do the headphones AC provides on the YYZ-LHR route come with a single point or double point (I'm travelling in J, in case there is a difference)? I last flew transatlantic 2 years ago and for the life of me I can't remember.

I will be bringing my laptop to entertain the kids with a DVD and it has a jack for the single point headphones. I won't bring my set from home if AC provides the single point kind.

Thanks.
