We went to Europe two years ago flew on British Air and United. Took 16 rolls of color and B&W. At the airport when we tried to have them hand check it they opened all the boxes and the canisters and then ran it thru the xray machine. we put the film in our checked luggage for the return trip and when we got it developed back home it was all fogged. the high spd asa 400 and 800 were worse than the asa 100 rolls.
We should have had the film processed in europe and jsut not worried about the expense.
