Do I Fly With Fountain Pens? Yes, I Do! (2026 San Francisco Pen Show Edition)

August 26, 2026

I’m on my way to the San Francisco Pen Show, where I’ll be co-hosting a maker’s panel tomorrow night, helping out at the Vanness Pens table through the weekend, and teaching two workshops on notebook systems: one on Saturday and one on Sunday! If you’re attending and want to sign up (space permitting), check out the events page on the show website. There is no charge to attend any of the events I’m associated with, but due to space constraints sign-up is required.

Flying with Fountain Pens: Do’s and Don’ts

Given that I have a four-plus hour flight ahead of me, I thought it made sense to discuss another topic of discussion that comes up weekly, both online and in the shop: Do I fly with fountain pens? The answer is absolutely, yes. I’ve successfully flown with fountain pens for years, mainly as a result of two pieces of advice I received early on.

Tip One: Fly with the Fountain Pen Full or Half Empty

Most “inkcidents” on airplanes occur as the result of air in the ink reservoir expanding due to pressure changes, which pushes ink into the cap and causes a mess when you uncap the pen to write on the plane or after you land. The solution is to (1) fill the pen completely before departure or (2) empty the pen and take ink with you to fill upon arrival. Personally, I follow the first approach, but I also take a secondary precaution by limiting the types of pens that I fly with.

Opus 88 is the most accessible maker of Japanese-style eyedropper fountain pens, featuring JoWo nibs and, of course, the stopper shown here.

Tip Two: Consider Flying with Vacuum-Fillers or Japanese-Style Eyedroppers

These days, if I’m flying with fountain pens, it typically will be a Japanese-style eyedropper (like an Opus 88) or a vacuum-filler (like the Pilot Custom 823 or the TWSBI Vac700R). In the past, I’ve had plenty of success flying with standard piston fillers and cartridge/converter pens using the “full or empty” trick discussed above, but both the Japanese eyedropper and vacuum-filler pens feature a valve system that allows you to seal the ink reservoir and prevent the bulk of the ink from leaking into the cap. (Occasionally you will still get a few drops from whatever ink is left in the feed or section.) Not only does this minimize the mess factor, but these pens also hold a ton of ink so you almost certainly won’t have to refill on the road.

If you want to write for a more extended session, and allow the ink to flow freely, simply loosen the blind copy to open the valve. You can still write with the pen with the valve shut - the section and feed usually will hold enough ink for a page or two, depending on nib size.

Bonus Tip: Keep It Simple

Don’t overdo it and pack a dozen inked fountain pens for a plane trip. The more pens you take with you, the greater the chance one leaks. I’m road testing several new eyedroppers from Opus this weekend, but I could easily see myself packing just one or two of these pens for more extended travel in the future. Stay tuned!

While we are away, the Nashville Shop will remain open Thursday and Friday from 1-6pm, and Saturday from 10am-4pm (Slightly reduced hours). Online orders will continue to be processed but shipping time for orders placed after Wednesday at noon will have a 3-5 business day fulfillment time as opposed to our typical 2-3 business days. As always, orders placed while we are away get a little something “extra” in them. Many thanks for your support!

Your Questions Answered: Flying with Fountain Pens

March 12, 2022

A common question I’m asked concerns fountain pens and travel, namely, “Can you fly with a fountain pen?” or “Can you take inked fountain pens on an airplane?” The answer I always give is “Yes”, with a few qualifications. I flew out to Baltimore on Thursday, and as my flight was sitting on the tarmac getting ready to leave Nashville, I realized that I had (inadvertently) packed five eyedroppered fountain pens, two Parker 51s with vintage aerometric filling systems, and a Lamy 2000, all of which were more than half-full of ink. Experiment time!

Instagram Poll Results

My first thought was to ask the readership (via Instagram): Which pens do you think will leak? Here’s what you all thought:

Two of the eyedroppers were Opus 88 Japanese-style pens with the shut-off valve, so I didn’t include them in the poll. Predictably, they didn’t leak.

Real World Results

And the “real world” test results? The only pen that truly leaked - meaning that it dumped a bunch of ink into the cap to the point where I had to rinse it out - was one of two Parker 51s with a vintage aerometric-filling system. Interestingly, a modern “fantasy” Parker 51 that used the same filling system but had a modern barrel and cap didn’t leak or even burp ink slightly. All three Schon Design eyedroppers had absolutely zero ink in the cap or on the nib, and my Lamy 2000 had a blob of ink on the feed that required me to blot it prior to writing. Importantly, I did NOT keep these pens “nibs up” during the flight. They were in my bag, in my pen case on their sides as I had to slide my backpack under the seat.

This unintentional experiment confirmed that you don’t have to worry excessively about flying with fountain pens. It’s never been something that I obsessed over, and these results are typical of what I’ve experienced over the years. Only one out of eight pens burped a significant amount of ink into the cap, though no ink leaked into my pen case, and that one pen was a vintage pen which I probably shouldn’t have flown with inked up anyway.

Tips and Techniques for Flying with Fountain Pens

If you absolutely want to minimize the possibility of a leak when flying with fountain pens, I might suggest the following general tips:

  • Fly with eyedropper/vacuum-filler pens with shut-off valves, such as Opus 88 pens, the TWSBI Vac700R, or the Pilot Custom 823 (among others).

  • Make sure any pens with other filling systems are full. This sounds counterintuitive, but it’s the expansion of air inside the filling system as air pressure changes that pushes ink out of the nib during a flight. If you remove the air by filling the pen immediately before taking off, you have a smaller chance of a leak.

  • Remove your pens from your carry-on bag and fly with them nibs-up in the seat pocket in front of you. Just don’t forget to take them with you when you deplane. I’ve heard horror stories.

  • Don't fly with vintage pens inked, especially vacumatic and aerometric filling systems. I’m no vintage pen expert, and can’t say why specifically these pens (in my experience) tend to leak more often than modern pens, but I suspect it’s due to modern feed/section/housing designs that minimize leakage. The majority of airplanes leaks I’ve experienced have involved me flying with vintage pens to or from a pen show.

Again, these are not absolutes, and there are no guarantees that you won’t have an issue, but I’ve had a lot of success flying with fountain pens and regularly do so.

Check Out My Instagram for Real-Time Photos of the 2022 Baltimore Pen Show!

I’ve been posting a series of pictures from the 2022 Baltimore Pen Show, ranging from crowd photos to vendors to nib grinders. It’s a combination of posts and stories (the latter of which are saved to the highlights so they don’t expire), and I’ll continue through today. To give you some examples of what you can find at the show, I picked up several inks from the Laban “Greek Mythology” series, took delivery of some specialty nib grinds I ordered from Custom Nib Studio (Gena Salorino), and had nibs ground in person by J.C. Ament (The Nib Tailor) and Josh Lax (J.J. Lax Pen Co).

Also, to celebrate the Baltimore Pen Show, and to compensate for the fact that I don’t have a table, all orders placed in the Curated Shop while I’m traveling this week will receive a free gift, and I’ve also added some new items from my personal collection to the Gently Used page.
