Every expat's worst fear is dealing with an emergency back home from far away. My wife and I are US citizens living in New Zealand. For us it's the question of how we would afford travel back home in the case of a family emergency, and would we even be able to get there in time?
The obvious answer is to have a budget and to make sure you keep enough in savings to deal with these kinds of emergencies. We do this, but how much is enough? What happens if we have to deal with a major car repair the day before we find out my sister had a horrible car accident? And really, who wants to be forced into performing the cost/benefit analysis of a $5,000 plane ticket in the context of uncertainty over whether or not a family member is actually in serious condition? If they are in serious condition, you have to leave now. If not, you've just wasted $5,000, but you might not know for certain until it's too late to get there in time.
Are there expat-focused insurance programs which pay for round-trip travel to your home country under certain emergency situations? I know there are travel insurance programs with similar features, but I'd imagine an insurance program focused on just this problem, just for people residing in a foreign country, would have cost benefits over typical travel insurance.
As an aside, I've written a bunch of rhetorical questions in this post. I'm only looking for an answer to the one in bold.
