I'll be flying out soon for some on-site interviews to a city I'd rather like to see. Would it be inappropriate to ask the company, who is already paying for my flight regardless, to schedule a later return date, say through the weekend? I have classmates from undergrad in the area who are willing to host me, so I could offer to have them not book a hotel room. This would likely be cheaper for the company overall. The company has not yet booked my flight.
I'm in the US, in the tech industry. The job is located in this city and I'd relocate there if I were to accept.
