Yes, you can generally bring a vape on a plane if you’re under 21, but there are some important guidelines to follow:

1. Carry-On Only

• Vapes and e-liquids should be kept in your carry-on luggage, not checked baggage. Most airlines and the TSA require this.

2. Liquid Restrictions

• E-liquids must comply with the TSA’s liquid rules: containers should be 3.4 ounces (100 ml) or less and fit in a quart-sized bag.

3. State Laws

• Be aware of the laws regarding vaping in the state or country you’re traveling to, as they can vary significantly.

4. Usage on the Plane

• You cannot use or charge your vape during the flight. This includes in the cabin and in the restrooms.

5. Airline Policies

• Check with your airline for specific policies regarding vaping and e-cigarettes, as some may have their own restrictions.

Conclusion

While you can bring a vape on a plane if you're under 21, it’s crucial to follow all regulations and policies to ensure a smooth travel experience.
