Hi everyone. I have at last summoned up the confidence to go on only my second holiday since being diagnosed Type 1 two and half years ago aged 55. I visited Canada my favourite destination and had a letter from my GP to show the airport staff and flight staff etc I was not asked for the letter at any time. The letter is dated 22 11 2011, My question is does anybody know if a new letter will be required this time bearing in mind my condition and medication has not changed. Thank you, regards Carole
