Yep, he was is going on a skiing trip for the last few days of his parents visit. I think he will not even be here on the day of their flight, so they will have to make their own way to the airport which is an hour away. It seems that he is so lost in the vast wilderness of MLCland that he doesn't even consider the implications of his actions at all.
