I watched a show on Court TV about travel safety tips, and they gave a very alarming statistic:
They said about 90% of those who cruise do not have health/medical/interruption coverage that would cover the cost of a helicopter evacuation at sea. They said the source of this data was the cruise lines themselves. What seems to be implied, but not said, is that Americans feel secure travelling on their corporate health benefits, not knowing that such an eventuality is not covered.
Not my problem, but a lot of folks have to pocket out, it appears.
