A missed connection in Frankfurt. A twisted ankle on a wet step in Lisbon. A suitcase that decides to spend the week in Doha instead of Marrakesh. Most trips go smoothly, which is exactly why insurance is easy to ignore until the moment you need a phone number and a promise in writing. A basic policy does more than many travellers assume, and rather less than plenty of them discover too late. Knowing which is which takes twenty minutes and can save you a four-figure argument.

Here is what the standard cover generally includes, where the gaps tend to appear, and what to ask before you pay.

What a standard policy actually pays for

Most travel policies are built around the same core: emergency medical treatment, evacuation and repatriation, cancellation and interruption, baggage, and personal liability. The limits and the conditions vary enormously, but the shape is familiar.

Emergency medical costs. Treatment for an illness or injury during the trip, hospital stays, prescribed medication, and sometimes emergency dental care for sudden pain. In many countries you will be asked to pay, or to guarantee payment, at the admissions desk. That makes the insurer's assistance line as important as the headline limit on the certificate.

Evacuation and repatriation. An air ambulance or a medically supervised flight home can be the single most expensive item in any claim. Check that evacuation has its own limit, separate from the medical limit, and that it covers getting you home rather than merely getting you to the nearest suitable hospital.

Cancellation and interruption. Cancellation usually reimburses the money you cannot recover elsewhere when you cancel for a listed reason: illness or injury, a death in the family, sometimes jury service. Interruption covers the unused portion of a trip and the cost of getting home early. Claim your refunds, vouchers and credits first — insurers normally pay only the shortfall.

Baggage and delay. Cover here is rarely generous. Expect a total cap, a much lower per-item cap, and a delay benefit that pays a small amount for essentials after a set number of hours, usually against receipts.

Personal liability. If you damage someone's property or injure them — a bumped table, a bicycle collision — this section can cover legal costs and compensation up to a stated limit. It is the part almost nobody reads and almost nobody regrets having.

The assistance line. A 24-hour number staffed by people who can authorise treatment, arrange transport and tell you which hospital to go to. In a real emergency, this is the most useful thing you bought.

What it usually doesn't cover

Cheap policies are rarely cheap by accident. They are cheap because the exclusions are wide, and the exclusions live in a section that usually begins "we will not pay".

• Medical conditions you didn't declare. Anything you are being treated for, or have had in the past, may be excluded if you didn't tell the insurer at purchase.
• Adventure and "hazardous" activities. Off-piste skiing, scuba beyond a stated depth, motorbike riding, trekking at altitude, and sometimes plain cycling without a helmet. Most can be added for a premium.
• Incidents involving alcohol or drugs. Being over the limit, or injured while intoxicated, tends to void the claim.
• Unattended belongings. A phone left on a sun lounger, a bag under a bus seat, cash, jewellery, and often anything checked into a hold.
• Cancellation reasons not on the list. A change of mind, a busy period at work, or a wedding you'd rather skip. A "cancel for any reason" upgrade exists, but it typically refunds only a percentage and must be bought soon after your first trip payment.
• Known events. Strikes, storms or wildfires already announced before you bought the policy, and travel against official government advice.
• Pregnancy beyond a stated number of weeks, plus routine check-ups, elective treatment and cosmetic procedures.
• Administrative slips. Misspelled names, wrong dates, or a policy bought after the trip has started.

None of this is secret. It is simply buried in definitions and small print, which is why the exclusions page deserves your attention before the price comparison.

The fine print that decides a claim

Two policies with identical headline limits can behave very differently when a claim lands on a desk.

Pre-existing conditions

If you take regular medication, are waiting for tests, or have had surgery in recent years, say so. Most insurers run a short medical screening and will then either exclude the condition, cover it for an extra premium, or cover it outright. Answering honestly at purchase is the difference between a paid claim and a rejected one. If you are unsure how your medical history should be described, ask the insurer in writing before you buy.

The excess, and what "reasonable" means

The excess is the amount deducted from each claim, and it can apply per section rather than per trip. Many policies also pay only what is "reasonable and customary" for the place you were treated, not whatever you were charged. Both details change the real value of a policy far more than a five-euro difference in premium.

Duty of care

Policies require you to act sensibly: keep receipts, report theft to the police within a stated window, call the assistance line before non-urgent treatment, and never admit liability after an accident you may have caused. Miss one of these steps and a valid claim can still be reduced or refused.

Match the policy to the trip

Before comparing quotes, write down what the journey actually involves: a cruise, a week of skiing, a rental car, a long-haul flight with two connections, a chronic condition, expensive camera gear. Then check that each item is named in the cover rather than assumed.

Look at what you already hold, too. Some credit cards, home insurance policies, health plans and employers provide fragments of travel cover. They usually come with conditions — a maximum trip length, a requirement that the trip was paid for on that card, a limit that only applies abroad for a set number of days — but they can plug a small gap or reduce what you need to buy.

Frequent travellers should price an annual multi-trip policy against several single-trip ones, checking the maximum length of any one trip. And expect premiums to rise for destinations where medical care is expensive, because the potential bill rises with them.

Questions to ask before you pay

1. What is the emergency medical limit, and does evacuation come with its own separate limit?
2. Which activities are excluded, and what does it cost to add the ones I plan to do?
3. What exactly counts as a covered reason to cancel, and how much of my trip cost would I recover?
4. How much is the excess, and does it apply per claim or per section?
5. Will my medical history be covered if I declare it now?
6. What is the per-item baggage limit, and does the policy pay for delay as well as loss?
7. Is there a "known event" exclusion that could affect my destination right now?
8. What documents does a claim require, and how long do I have to submit it?

If a sales page can't answer these, call or email and get the answer in writing. An insurer that is vague before the sale will not become clearer after it.

After you buy: small habits that save hours

Save the policy number and the assistance line in your phone, screenshot the emergency page, and send a copy to whoever is travelling with you. Photograph receipts as you go rather than stuffing them in a wallet. If something goes wrong, call the assistance line before committing to a non-urgent treatment plan, keep every document, and file the claim inside the deadline — those windows are usually short.

Buy early, too. Cancellation cover generally starts when you pay, and a policy bought the night before departure covers almost nothing that could already have gone wrong.

Insurance rewards preparation and punishes assumptions. Read the exclusions, declare what needs declaring, pay for the add-ons your trip genuinely requires, and keep the paperwork somewhere you can find it at midnight in a foreign hospital. And since policies are contracts governed by local rules, if the sums involved are large or the situation is complicated, speak to the insurer or a qualified insurance adviser before you rely on a particular clause.
