Hi, DD is flying with a group from her school from St. Louis to Hong Kong with a stop both ways in Detroit(on Delta). We live near ORD. I would love to have her fly from Detroit to ORD on the return home instead of her flying into STL. Since this would be the last leg of the journey - is it OK for her not to board that flight? This is a group ticket. I would be happy to call ahead and cancel just that flight - but she is not the only one on the ticket and we did not book it. I have read that airlines will cancel your ticket if you don't board your booked flight on a multi-flight trip - but since this is the very last part, I was hoping this might be doable. Would really appreciate your advice. Thank you.
