Don't bring any bottled drinks or you'll be throwing them out before you get through security! Other snacks are fine
Snacks OK. But they don't allow more than 3oz of liquids.
No more than 3 ozs thru security, thats why the empty bottle. Fill it up inside for free, or buy the same bottle for $5.
You can on plane...if you don't want to buy water you can bring an empty water bottle thru TSA. You can bring food thru..just not liquids.
