My Daughter and I will be flying OKA to NRT via Fukuoka...return via HND, we used UAL miles to purchase the tickets. For whatever reason our tickets are considered international, we are connecting to a Delta Flight@NRT but are required to recheck in, so I have been told we are allowed 20kgs or 44llbs each person but what I can not get a straight answer on is how much is it going to cost us if we go over?

Any help would be much appreciated!
