Doing this at exactly T-24:01 got us both aisle seats in close proximity, which while not ideal is definitely better than middle Y seats on a nearly-full transpac.
That's good news! I just booked another itinerary with an NH segment and could not convince UA to use the NH flight number (they used to do it on request)
