Hello, let's get started. Most people buy travel insurance the way they buy a phone charger at the airport, grabbing whatever's at the top of the search results five minutes before checkout.

That works until you actually need to file a claim. Then you find out the $18 policy you bought covers almost nothing that matters.

Start with the medical number

The single most important line in any policy is the emergency medical limit, and the gap between cheap and decent is huge. Budget plans often cap medical coverage at $10,000 to $25,000, which won't get you far in a US hospital. A serious policy typically runs $100,000 to $500,000 in emergency medical and includes evacuation. If you're traveling to the US, Japan, or anywhere with expensive healthcare, look for at least $100,000. For a week in Portugal, a lower limit is fine.

What your card already covers

Before you pay for anything, check what you already have. Many credit cards include trip cancellation or delay coverage if you booked with them, and some travel cards carry limited medical evacuation. Call the number on the back and ask specifically about cancellation limits and evacuation. I've seen people buy duplicate coverage because they never checked. That's money you don't need to spend.

Read the exclusions, not the brochure

Every policy has a list of things it won't pay for, and that list is where the real decision lives. Common exclusions include pre-existing conditions, extreme sports, and travel against government advisories. If you're going scuba diving in the Red Sea or skiing in Colorado, a standard policy won't cover you unless you add a rider. Pre-existing conditions are trickier: many insurers waive that exclusion if you buy within 14 to 21 days of your first trip payment.

Match the policy to the trip

A two-week beach trip and a six-month backpacking route need completely different products. For a short, simple trip, basic cancellation plus medical is enough. For long-term travel, look at annual multi-trip policies, which often cost less than two single-trip plans and cover unlimited trips under a set number of days each. If you've spent $4,000 on a safari, insure the full trip cost, not just the deposit. Cancellation coverage generally reimburses only what you've actually paid.

Check the claims process early

A policy is only as good as its claims desk. Look up the insurer's claim rating before you buy, and note whether they require receipts, police reports, or doctor's notes for common claims. Some insurers let you file through an app with photos; others want paper forms mailed in. That difference matters when you're stuck in a hotel room in Bangkok with a stomach bug and no printer.

The takeaway is simple: pick your medical limit first, confirm what your card already covers, and read the exclusions before you pay. Do that, and you'll never be the person discovering a $25,000 cap from a hospital bed. Next time you book a flight, spend ten minutes on the policy before you hit buy.
