Can you bring a mirror on a plane? In both carry-on and checked baggage, you may bring a mirror on a flight. The Transportation Security Administration (TSA) and the majority of airline regulations do not expressly forbid mirrors. But there are a few things to think about. Make sure the mirror complies with any size and weight restrictions the airline may have for carry-on or checked luggage. It is advisable to confirm the rules with your particular airline as these limitations can differ.
