We have recently travelled from Melbourne to Hawaii (2 islands) to San Francisco then returned from Las Vegas to Auckland (3hr stop over) back to Melbourne. I thought I might have to have hand luggage scanned in Auckland which would have meant my 30 rolls of exposed and 9 unexposed rolls of 35mm film going through 7 x-ray scanners, which could have fogged all my 400 ASA film. So my thanks to all airport security staff who graciously obliged to hand inspect my film every time with no argument about it being okay to scan 400 ASA. This is what I did. Left all new film in its original plastic packaging. Packets of 10 x Tri-X leave the plastic wrapping on as you extract any boxes to use so say 7 unused boxes are still in the wrapping for the original 10. All other rolls (not in plastic canisters), whether developed or not, put in clear plastic zip bags When at security put all the film in a seperate tray and ask for a hand inspection very very nicely as this takes up security staff time. I found every airport staff extremely obliging. They take the tray for chemical analysis every time and then to their supervisor for further inspection and approval. They are all interested in the safety of your film. Congratulations to our world airline security personal for looking after us old school film photographers. Robin.
