I'm due to fly tomorrow on a 4.5 hr flight and return next Saturday, so away for a week but am unwell. . I suffer with sinus but I have horrific ear ache with it this time and really don't think I can fly with the pain. I am to attend my Doctor later today in case I need am antibiotic. My question is, if I asked him for a letter for my travel insurance company to say I shouldn't fly, would I be able to claim back for my holiday? Thanks x
