Answered by Michael Wilson

As an expert, I can provide you with detailed information about self-defense weapons that are allowed to be brought on a plane. It’s important to note that regulations may vary depending on the country and airline, so it’s always advisable to check with the specific airline and airport authorities before traveling.

1. Mace or Pepper Spray:
A 4 fl. oz. (118 ml) container of mace or pepper spray is generally permitted in checked baggage. However, it must be equipped with a safety mechanism to prevent accidental discharge. This is important to ensure the safety of both passengers and crew members during the flight.

2. Tear Gas Concentration:
Self-defense sprays containing tear gas, such as CS or CN, are generally prohibited in checked baggage. However, if the tear gas concentration is below 2 percent by mass, it may be allowed. It’s crucial to check the specific regulations of the airline and airport to ensure compliance.

3. Stun Guns or Tasers:
Stun guns or tasers are generally not allowed in carry-on or checked baggage. These devices are considered as prohibited weapons due to their potential to cause harm and disrupt the safety of the aircraft. It’s important to leave stun guns or tasers at home when traveling by plane.

4. Knives and Sharp Objects:
Most knives and sharp objects are not allowed in carry-on baggage. This includes items such as pocket knives, box cutters, and utility knives. However, these items may be allowed in checked baggage. It’s essential to pack them securely and follow specific guidelines provided by the airline or airport.

5. Personal Alarms:
Personal alarms, which emit a loud sound to alert others in case of danger, are generally allowed in both carry-on and checked baggage. These devices are often small and compact, making them convenient for travelers to carry for self-defense purposes.

6. Kubotan or Tactical Pens:
Kubotans or tactical pens are small self-defense tools designed to be used as keychains or writing instruments. These items are generally permitted in both carry-on and checked baggage, but it’s always advisable to confirm with the airline before traveling.

7. Whistles:
Whistles are commonly used for self-defense and attracting attention during emergencies. They are generally allowed in both carry-on and checked baggage. It’s a good idea to keep a whistle accessible in case of any unforeseen circumstances.

Remember, it’s crucial to always check the specific regulations of the airline and airport you are traveling with to ensure compliance with their guidelines. Additionally, it’s important to use these self-defense tools responsibly and within legal boundaries.
