Thx for the tips/info all.
I cant make it to the meeting Sat., i'll be out of town.
I actually did navigate thru American Airlines automated call menue, long enough to reach an option, to talk to a real live person! She told me that in the 25 years she worked there she had never been asked that question ...lol. Anyhow, carrying it on is pretty much out of the question. Putting them in your checked baggage is ok to the best of her knowledge. I have some small plastic specimen sample containers with screw on caps. I will put the frags in them. I plan on buying a cheap lunchbox style insulated cooler to put em in. How many hand warmers should be put in the "lunchbox"? Should the warmers be right up against the containers or spaced off them with bubble wrap or something?
