My boyfriend is going out of state for business and he wants me to go with him. I know generally SO's do go if they have time themselves. Can/should he just bring me or is it up to the company? He will be gone for 3 weeks and would like me to be with him. He had suggested that he wanted to drive the 13 hours vs flying and HR asked why? We would rather fly since they're paying for his ticket and expensives anyways and my ticket would just pay be out of pocket. They pay for his rental car too but it's a shared rental car with another employee. Would it just be best for him to tell them he prefers to have his own rental car if he flys or is he better off just telling them its a personal preferences of driving there?
