In flight or going through security.As stated, the cabin is pressurised to 7-8000ft and modern airliners are pressurised to even lower altitudes. So with the limits being stated as 10,000ft (which I didn't know!) it'll operate just fine. With regards to accuracy, I've just experienced typical Libre accuracies as you do on the ground. I have to keep within 5-15 mmol/l whilst flying and the Libre sees me to within 1-1.5mmol/l of my actual blood glucose reading. Usually within 1 mmol/l.It might have just been the sensor, but if I apply a new sensor in the morning, then I'm off to work in the afternoon, I find the readings are a little more inaccurate. If I apply it on my days off and it's had 48-72hrs being on the ground, it's much more accurate. I could just have been that specific sensor however.</blockquote>
