Even if I have to pay for the checked bag @ $25.00 it is still cheaper than ordering the supplies and having them delivered to Hawaii. I have also checked the local Walgreens on Maui as I am unsure if we have even packed enough of the adult diapers (can't fit any more in) and they have the product we need in case we run out. Although, the price on Maui is about 1/3 more than we would pay here at home.
Before American Airlines changed their website I was able to find the exclusion for medical supplies in checked bags, but once their website got upgraded, I can't find it.
