Can I bring my favorite pen on a plane? Well, this question has kept me confused for a long time and the same might be true with you. However, understanding the rules and precautions can make your trip smoother, whether you’re carrying gel pens, fountain pens, or even highlighters. This comprehensive guide covers everything you need to know about bringing pens on a plane.

Frequently Searched Queries About Pen on a Plane
I tried to answer some of your most-asked questions one by one in a simple and clear way.
Can You Bring Pens on a Plane?
Yes, you can bring pens on a plane! Pens are completely allowed in both your carry-on and checked luggage. There are no restrictions from TSA and airlines on carrying pens, so you can travel with ballpoint pens, rollerball pens, gel pens, or mechanical pens (conditions applied) without any issues.
These tips are for those who are frequent travelers or need to bring multiple pens on a plane:
- Keep your pens organized in a pouch or case to avoid losing them in your bag.
- Place them nib-up to prevent any accidental ink leaks, especially during cabin pressure changes.
Are Fountain Pens Allowed on Planes?
Fountain pens are definitely allowed on planes without any issue. However, the misconception arises due to the risk of ink leaks caused by cabin pressure changes. To prevent leaks:
- Empty the ink or store the pen nib-up.
- Use resealable bags to contain potential spills.
Why Do Fountain Pens Leak on Planes?
Fountain pens leak on planes due to changes in cabin pressure during the flight. The pressure difference forces air inside the pen to expand, which pushes ink out through the nib or feed, causing leaks. Storing the pen nib up or emptying it before flying can help prevent this.
Can I Bring Gel Pens on a Plane?
Yes, you can. You don’t need to search a lot. According to ICAO and TSA rules, gel pens are allowed on planes. You can carry them in your hand luggage or checked bags. However, it is always advised to pack them securely to avoid leaks.
How Many Pens Can You Take on a Plane?
Frankly speaking, there is no specific limit on the number of pens you can bring. Feel free to pack as many as you need, but bulk quantity may cause customs-related issues.
Do Pens Count as Liquid on Planes?
Pens themselves do not count as liquids. However, ink refills fall under the TSA’s liquid rules and must comply with the 3-1-1 rule if carried in hand luggage. According to this rule, the liquid must not exceed 100 ml.
Will Pens Explode on Airplanes?
The pen explosion incidents during flights are very rare in the history of aviation security. However, due to cabin pressure, some pens, especially fountain or gel pens, may leak. To avoid this, you can store them nib-up or empty the ink before flying.
Are Brush Pens Allowed in Flight?

Can I bring a highlighter to a plane?
Yes, highlighters are allowed in both carry-on and checked luggage. Keep the caps tightly secured to prevent them from drying out.
