As an expert in the field of aviation security and passenger guidelines, I can provide you with a comprehensive answer regarding the question of bringing a mirror on a plane.

First and foremost, it is important to understand that airline security and the **Transportation Security Administration (TSA)** have specific rules and regulations regarding what can and cannot be brought onto an aircraft. These rules are in place to ensure the safety and security of all passengers and crew members on board.

When it comes to carry-on items, there are general guidelines that apply to most airlines. As you mentioned, sharp items are typically restricted, and this includes items like razor blades, knives, and other cutting tools. However, mirrors are not explicitly mentioned in this category.

The dimensions of carry-on luggage are another important factor to consider. The 45 linear inches rule you referenced is a common guideline, which means that the total of the height, width, and depth of your carry-on bag should not exceed 45 inches. This is to ensure that the luggage can fit in the overhead compartments or under the seat in front of you.

Now, regarding the specific question of bringing a mirror on a plane, there are a few considerations:


1. Size and Dimensions: If the mirror is part of your carry-on luggage and its dimensions, along with the rest of your luggage, adhere to the airline's size restrictions, then it should be permissible to bring it on board.


2. Sharp Edges: If the mirror has a sharp edge or is part of a compact that includes other sharp items (like a compact with a built-in razor or tweezers), it may not be allowed in the carry-on luggage and would need to be packed in your checked luggage.


3. Material: Some mirrors are made with materials that could potentially be mistaken for a weapon or used as one. In such cases, the mirror may be subject to additional scrutiny or may not be allowed at all.


4. Airline Policies: It's crucial to check with your specific airline for their policies on mirrors and other items, as these can vary from one carrier to another.


5. Security Screening: At the security checkpoint, all carry-on items, including mirrors, will be screened. If the mirror raises any security concerns, you may be asked to remove it from your bag and undergo additional screening.


6. Packaging: If you are bringing a mirror, it is advisable to pack it securely to prevent it from breaking. This could involve wrapping it in clothing or using a padded case designed to protect fragile items.

7.
Liquids: If the mirror is part of a cosmetic item that contains liquid, remember that liquids in carry-on luggage are subject to the 3-1-1 rule, which means each container cannot hold more than 3.4 ounces (100 milliliters) of liquid, and all containers must fit into a single, clear, resealable plastic bag.

In conclusion, while mirrors are not specifically mentioned in the general guidelines for prohibited items, it is essential to consider the size, sharpness, material, and airline-specific policies when deciding to bring a mirror on a plane. Always check with your airline before traveling to avoid any inconvenience or delays at the airport.
