My DH is an insulin dependent diabetic and carries his equipemtn everywhere - his insulin, blood glucose tester, and his syringes. Will he have a problem at airport security because of the syringes? I do not want him to be without his kit. Should we get a letter from his doctor stating that he is indeed an insulin dependent diabetic and should carry his supplies with him at all times? I just don't want the security personnel confiscating his kit at the checkpoints and not having access to his supplies during a 3 hour flight. Beverly Lynn or anyone else who knows, can you please let me know??
