Here's why:
* TSA Regulations: The Transportation Security Administration (TSA) prohibits lighters in both carry-on and checked bags. This is due to safety concerns related to potential fire hazards.
* International Regulations: Many international airlines and countries have similar restrictions.
* Alternatives: You can purchase lighters at your destination if needed.
Important Note: Even if you're not traveling by airplane, check the specific regulations of your mode of transportation (bus, train, etc.) regarding lighters.
