@karenps I agree with all the great tips other members gave you: a carry on bag for all your prescriptions & medical gear plus frozen gel packs to keep meds (like insulin) cold. Your doctor can give you a letter explaining your need for this. I keep a copy in my luggage and have one in my purse too. I keep suitable snacks in the glove compartment of the car, the night stand by my bed and my purse so that if the low blood sugar strikes I have what I need readily available. Glucose tablets &/or gel can stay there indefinitely because there’s no need for refrigeration. Life Saver candies are a good option too. Also, not a liquid to worry about (spilling or size). Regarding liquids, buy travel size hygiene products and put in a make up like bag in checked baggage. You can use zip lock bags around them too if you’re worried about spillage. If something (God forbid) happens to your luggage, that stuff is easily replaced when you get there. Or chances are you can mooch off of your friends. It is your personal medical stuff that requires most care.
I’ve never had a problem going through the scanners with my devices on my body but it has been awhile since I’ve traveled. They can run their wand like thing around / over you. The “pat down” term creeps me out and sounds like prison. Have them hand check the carry on. Have your Dr. letter document handy to present. Enjoy your trip and seeing your friends. Let us know how it goes?
