Chris, thanks for those links! I did do a search before I posted this topic. Those are the older security issues. Now the checked baggaged is screened and hand searched, so even more stringent rules apply. So I can not find what - within the USA - rules are. But I know time is running out.
I'll try and call some of my buddy's at Delta in the am and see if I can post some info for all here.
I think my parachute is going to start not opening!
