Emergency Remedial Assistance provides insurance and medical assistance for travelers. It would protect you if you had to be taken off a mountain as a result of a skiing or hiking accident, or if you had to halt for a lengthened period of time in a foreign hospital. Insurers would also give insurance cover if you got seriously sick or were injured and had to be flown home. A number of commercial airlines require extremely sick passengers to fly on a stretcher with a doctor. Generally this means that you may have to buy 10 or more seats on a plane at a likely pot cost of over $10,000.
Ahead of purchasing this sort of coverage, ensure with your specific health insurance carrier. Find out what form of coverage you contain when traveling abroad and if there are any limitations. In addition, inquire if the policy will compensate to fly you home or to a country with first-rate medical care.
