Only time I have had an ‘issue’ at airport security was returning through Gatwick earlier this year when one of the personnel checking stuff into the bins saw I had pulled a new CGM out and said.. mm they’re not supposed to go through the X-ray machine are they? This is what I had read.. but nobody seems to take notice of it, had one fail on me after it had been through an X ray machine in its box. Nice understanding girl passed the new CGM through the security line and said I could collect it the other end. A different security officer at the other end held up the yellow Libre box and asked whose it was and he called me over to the side of the security line, asked if I had Type 1 diabetes, and then told me so did he! I was so stunned I couldn’t say anything… he wished me a good day and I think I managed to stumble out the same to him.
