Can you bring hair straighteners on a plane? Absolutely yes. In carry-on? Yes. In checked? Yes. With a cord? Yes. Without a cord? Check the battery rules. That’s it.
So go ahead. Pack your styling tools. Keep your hair game strong. Just don’t try to straighten your hair while waiting for the lavatory—that’s weird, and frankly, dangerous.
Now stop worrying, grab your straightener, and go have an amazing trip. Your hair will thank you. And so will your seatmate.
