Can you Bring Cigarettes on a Plane:- You may bring tobacco products on board as carry-on or checked baggage. However, smoking them while in flight is not permitted at any time. The TSA is very explicit that you can transport cigarettes through airport screening as carry-on or personal items, as well as stow them in your checked baggage. There are no restrictions on quantity or size, so you can theoretically bring as much as your bag can hold. As a result, you might need to undergo a more thorough screening, which could cause a delay in getting through security. However, if you have nothing to hide, there shouldn't be a problem even if you have multiple boxes of cigarettes.
