Before all this Covid stuff, I would have to fly to different areas for my job.
1. I have not had an issue with the TSA and scanning my carry on. One time I did open my suit case when I got home and found an inspection slip say they choose my bag randomly to search. I could only image the look on their face when they saw my supplies in zip lock bags and five days of clothes.
their is no need to notify them prior to anything. I would say something if you get pulled to the side for a pat down so they know they will feel padding around that area.
When my carry on bag was pulled from the inspection line, I quickly showed the agent my disability card and asked if the bag had to be empty could it be done in a private area. She told me what the issue was and I told her where to find my laptop. She pulled one of my laptops out and sent my bag back through. The reason was I had left my work and personal laptop in my bag which triggered it.
2. If I could get away with it, I would bring two carry on items with me. one for my clothes the other filled with my supplies. One would be a collapsible bag so I could fit it into the other.. Otherwise I would be a bring a bigger suitcase to check containing both. I still carried a few days of supplies in my carry on just in case my luggage was delayed or lost.
