So I took my DE pen on a flight today for the first time. The downward facing nib put some ink in the cap but the section had no ink on it. I just emptied the cap into a sink and rinsed it. The upward facing nib had no issues, just like all my other pens.
The result with the downward facing nib was as I expected.
Will this prevent me from flying with the pen inked? Nope!
