Tripods according to TSA - Straight from D.C.

The rules and regulations about what items may not be carried into scheduled airlines' airplane cabins is definitive. TSA (Transportation Security Administration) lists items in their Prohibited Items List which are definitively banned.

It's to be expected TSA can't list everything which might be a good idea to prohibit. There are far too many items that travelers might take in their carry-ons, to think any group of people could possibly imagine them all or even most.

Unfortunately, when we try to use the list to evaluate if a questionable item would be permitted or prohibited, we find it's virtually impossible to use the list to predict what a TSA TSO (Transportation Safety Officer) will decide.
