Hiya, i'll be flying to and from ireland when i'm 30-31weeks; i know i need a letter, but does it have to be from the doc, or can i just ask the midwife to do it? seems silly to get a doc's appointment just for this, esp as midwife knows my condition best. also, do you need to send these letters of permission to the airline prior to flying, or inform them in any way that you are pg, or do you just carry the letter with you in case they question you at the airport?
