I say you should keep your script for those too. It comes in the box when I order it. Also I keep the wallet card I got from MiniMED.
None has ever mentioned my sets. But I usually carry only 1 with me, the rest in my checked luggage. I keep lantus and Novolog and a syringe with me.
I was only ever questioned about my Insulin and My CGM which I just don't wear while flying outside the US. They looked at my script and my 1 syringe and let me go through, but Ive had it scanned millions of times and generally never gets any attention.
Times when I would declare I had on a pump, is a different story as they would take it away from me, out of sight to look at it, and I would be wanded 3 or four times and questioned. Then give it back and expect me to re connect it after its been handled. Even those times though, I was allowed on the plane and was no problem after that.
ALSO , NEVER ORDER THE DIABETIC MEALS ON INTERNATIONAL FLIGHTS.
You will be questioned about it and searched .
I don't know why, but It has happened to me every time I have done it.
The meals are rediculous any way. I once got a snickers bar as part of my diabetic meal which ended up vegetarian and carb heavy anyway,
Since then I keep it tucked in and it never causes any trouble at all.
