One member of our party, for an upcoming cruise, tests blood sugar levels once or twice a day. Although he does not have any meds or needles, is there a problem carrying lancets? Would he need a Dr.'s letter or is this not a concern at all? Thanks.
I carried lancets with me on numerous flights and cruises in the last year.
They were in my carry-on.
Although I had a doctor's statement I was never asked for it by any security personnel.
Agree that a doctors statement should be taken in case of questions.
