Just an update from my fit to fly post from over a month ago. I went to the airport with a letter from my doctor stating my condition, medication and saying that it is well maintained and stable at the moment. This was despite Tui saying that it must be a fit to fly certificate, if not I would be refused to board.
I had requested airport assistance. Nobody asked for anything to do with fit to fly. I had been quite worried before I went imagining the worst case scenario. Not to worry, I had a wonderful week in Gran Canaria, wish I could have brought some of their lovely warm weather back for us all.
