This is entirely up to you. However if it were up to me, I would be charging either a full day for checking in at that time or at least some prorated rate.
I look forward to seeing what other hosts would do in this situation.

First is that flight time actual. In Hawaii we have a lot of international flights so many come in late but it wasn't unusual and I remember coming in on a late flight was midnight. Airports don't close but I don't know of any 24 hour airline employees. Look at the situation before can I charge.
