Can you take aluminum foil on a plane?

Yes, you can take aluminum foil on a plane. It is allowed in both carry-on and checked luggage, but keep in mind that it should be used for its intended purpose, such as wrapping food. However, if the foil is in large sheets or used in a way that could be considered a security risk, it may be subject to additional screening. Always check with your airline and the TSA for the most current regulations.
