Asking for a friend who is on holiday in Spain. Her husband has has a heart attack, and been told by the Doctor there not to travel for 4 weeks. He has had 2 stents fitted and is making a good recovery. They have their own place, so claiming only for flights. Travel insurance saying that their doctors think he is fit to travel - he is afraid to and the doctor in Spain told him 4 weeks, is there anything they can do or say to the insurance to get them to cover the delayed flights?
