Hello. Mark who replied here is my insurance agent. I am not an expert on this topic let alone a professional. But Mark has helped me a lot. My first claim ever was in the past couple of weeks after I broke my ankle. His company worked immediately with the hospital to cover the part of the claim that they were liable for. They negotiated at 6:30pm on a Saturday evening and agreed their share within 30 minutes when I checked out. They had been informed when I entered of course. It was remarkable to me actually. My only comment is that you should consider too much coverage not too little if you want full reimbursement. And the other thing is that you will likely use public hospitals for small things and the cost of that is trivial. They are good too. But for something serious you might decide to go to a private hospital for all kinds of reasons including having many staff who are fluent in English. The costs then can be substantial. Nothing as horrendous as the US but not small. You need to decide if you want to be fully covered. It depends how risk averse you are. And how rich. Good luck.
If he travels as much as stated he will have hundreds of thousands of miles in his airline account. In 3 minutes he can get a mileage ticket to anywhere. I don’t believe half these stories.
