Just had a Belizean friend come for a visit.
After I called AA and figured out that she was going to have to either pay $25 bucks a bag for being overweight at 51 to 70 or take a third bag that would cost a $100.
She said maybe we can mail it home.
The US post office is asking $47.85 to mail a 20 lb package to Belize with a delivery date of anywhere from 2 to 6 weeks, plus you have to fill out a customs declaration form.

Eventually she saw the light and paid the extra $25 for being 20 lbs overweight on one bag.
Thank goodness she went back the week before they had the no liquids in carry on or we would still be at the airport trying to repack.
