Can you bring a water bottle to the airport?
Also, can you take an empty metal water bottle on a plane?
Yes, water bottles are allowed as a carry on item. Just be sure they are empty as you pass through the TSA checkpoint.
Likewise, why can you not bring water on a plane?
The Real Reason You Can't Bring Water Bottles Through Airport Security. For a mode of transportation that can cause dehydration, not allowing water bottles through security is particularly grating. The directive was put in place by the Transportation Security Administration (TSA) in 2006.
You can carry cakes, fruit, vegetables, sandwiches and all solid foods in your hand luggage. You can put these items in your hold luggage to minimise delays. You are allowed to carry empty water bottles through security in your hand luggage, so take the environmentally conscious route and invest in a reusable bottle.
