So I'm flying next week (I'm in the US), and will need to do my shot while I'm gone. I don't usually check luggage so I plan to bring my T, the needle/syringe in its packaging, and a doctor's note in my carry-on luggage. Anyone have any experience with this? The airline charges around $25 to check luggage, so I'd really rather just carry it on. Hoping the doctor's note will be enough for the TSA and I can just bring my stuff on board.
