I've been travelling with film all my life.
Remember back in the very late 80's buying 2 X-ray proof film box from Posso (rebranded by the now extinct french "Phox" reseller) which took with me around the world, even to and from St. Petersbrug back in 1993. Never, ever had a single complaint about them or their use, but that was early to mid'90s
Later on I just stopped using them and had not any concerns apart from some fogging in one colour roll 4 years ago in which my poor camera was scanned multiple times (don't remember where it was, maybe Istambul Airport).
But the most important threat regarding my film was in Stansted Airport when the officer, besides scanning those "weird canisters" wanted to see what was inside. That became an argument until his/her superior came and told they were simply films.
To make a long story short, seems that no one cares nowadays about film. No labels are stuck on film scanners, there is an absolute lack of knowledge regarding photographic products and we are regarded as some freaks from the 20th century trying to slow the pace of security inspections. Any Security Officer below 40 might not even know what film is and nobody might have trained him because, regarding statistics,film users are represent a really really tiny amount so it's not considered necessary.
In the US, being Kodak Alaris a US Business, and producing motion picture films, the campaign and talks with TSA migh have helped to raise some concern regarding the use and effects of CT scanners. But for the rest of the world, think we are done.
As many of you, I stopped flying due to pandemic and restrictions, and fear,as most of you, what can happen.
A friend of mine works in a Spanish airport, might ask him not regarding film, but about the x ray proof film box and will report back.
Best regards
