Can I take my makeup mirror on a plane?
You can take your makeup mirror with you on a plane as long as it meets the standard dimension allowed by most airlines which is 45 linear inches (the total of the height, width, and depth of the bag) and the standard weight of a carry-on luggage 40 pounds for most airlines.
Makeup mirrors for travel are generally compact/handheld, so it should be safe to take them on a plane.
The final decision rests with the TSA officer on whether an item is allowed through the checkpoint. Different airlines have different policies on allowed and prohibited items. It would be best to check with the airline first before you travel.
