What about snow globes? You can bring them, but only if the liquid inside is under 3.4 ounces. So, tiny snow globes are fine. The big ones? Check ‘em.
Can you bring a fishing rod? Yes, but only as checked luggage. The TSA does not approve of aerial trout fishing in the terminal.
And human remains? Yes, you can fly with cremated ashes. Just pack them in a non-metal container and be ready for a X-ray inspection. It’s weird, but it happens more often than you think.
