I recently took a business trip to NYC and Amsterdam. It was long enough that I decided to take my Model 01 in the Keyboardio carrying case.
At both JFK on the way to Amsterdam and LAX on the return from Amsterdam transferring to a domestic flight I got pulled aside for additional screening including swabbing all my belongings and the full pat-down because of the Model 01 in the case.
At LAX I even got to meet the TSA Explosives Expert on duty. Apparently the circuit boards, wires, and wood case combination really freaks the TSA screeners out. The wood appears as “organic material” and next to the electronics it looks suspicious.
Just a heads up for anyone that wants to travel with their keyboard, you might freak out some TSA agents.
