What Travel Insurance Might not cover.

Depending on the coverage you choose, travel insurance can cover a broad array of possible damages and losses:

Travel insurance can help protect you from medical expenses abroad that your normal health insurance doesn’t cover. Most health insurance plans don’t provide full coverage in foreign countries and some health plans provide no coverage at all, including Medicare. Travel insurance works in addition to your everyday health insurance and can help supplement medical costs if you get sick or injured before or during your vacation.

Travel insurance can help cover expenses stemming from lost or stolen luggage. This is especially useful if an airline loses your bags, as it can be very difficult to get them to pay for lost luggage. In the United States, the Department of Transportation (DOT) requires airlines to compensate fliers up to $3,300 for lost baggage. In foreign countries that amount is a maximum of $1,750. But to receive those maximum amounts, passengers must provide receipts proving the value of the lost bags and their contents. And some airlines require that the claim be filed within 21 days.

To make matter worse, DOT doesn’t define when baggage is officially lost (as opposed to just “delayed”). Overseas, a bag is only considered “lost” after 21 days. For delayed bags, DOT only requires airlines to provide victims with enough money to buy necessities like clothing, medicine and toiletries.

Travel insurance can help cover costs stemming from trip cancellations. Most resorts or cruise lines won’t give you a full refund in the event of a cancellation. If you cancel two weeks or more before your trip, most resorts will at least charge a cancellation fee; many cruise lines might only give you a 25% refund or will give you partial credit on another cruise. If you cancel within two weeks of a trip, with most companies you won’t give any refund whatsoever. Unforeseen circumstances happen, and you want to be covered just in case.

Some credit cards provide limited coverage, with annual limits and restrictions for cancellations and interruptions (if they offer cancellation/interruption coverage at all). However, few credit cards offer coverage for the most expensive travel risks: medical expenses or emergency evacuations, which travel insurance can cover.
