I hope it works out, very sorry to hear news of your father.Trying to get a refund for a flight with United. My dad was scheduled to have his kidney removed (cancer) but they canceled due to concerns his heart is not strong enough to survive the surgery. They will do more tests and potentially reschedule. I did buy trip insurance. I don't fly that much outside of work travel and have never gone through this process. It isn't as straight forward as I hoped. Just requested a refund and then apparently after that, depending on the outcome, I can make an insurance claim. Just getting to this point, I think the most frustrating thing is the automated phone crap. Please just let me talk to a human.
