Your daughter may fit differently in the
Nautilus than in the
Regent when they are installed. The top slots are 18.5 inches in the
Nautilus.
I think the
Nautilus will work best for you. If she doesn't fit...a Cares harness on the plane, and do you have someone in Norway who can have a seat for you when you arrive? You're daughter may be able to ride
RF there.
