My girlfriend was coming to visit me in state a, coming from state b. My plans changed and I will be able to drive her from state b to state a the day before her flight instead. This is the option that she wants. Her dad bought her a round-trip ticket from state b to state a and is unable to cancel the first ticket without losing money.
Will he be notified if she does not use the ticket for the first leg? They don't have the best relationship but she'd rather drive with me than fly and doesn't want to make him that mad.
