Crisis Health Aid supplies insurance and medical assistance for travelers. It would protect you if you had to be removed off a mountain due to a skiing or hiking accident, or if you had to halt for a lengthened period of time within a foreign hospital. Insurers would also offer cover if you got acutely sick or were injured and had to be flown home. A number of commercial airlines require exceedingly sick passengers to fly on a stretcher with a doctor. Ordinarily this means that you might have to purchase 10 or more seats on a plane at a potential pot cost of over $10,000.
Before purchasing this sort of coverage, make sure with your particular health insurance carrier. Find out what form of coverage you have when traveling abroad and if there are any restrictions. In addition, request if the policy will compensate to fly you home or to a country with first-rate medical care.
