Can you bring Grizzly pouches on a airplaine?
Technically, no you cannot. However, I've done it several times
without incident. The best way is to get a small coffee from the
airport that you can bring on a plane and after drinking most of
the coffee, leave a couple ounces in the bottom. Then when you need
to spit, simply pretend like you're taking a drink from the coffee
through the lid and spit into it.
Again, TECHNICALLY IT IS NOT LEGAL, however, if you are discreet
about it you will be ok with no problems. Worst case, if you do
happen to get "caught," they will just tell you to take it out and
not do it again.
