What Travel Insurance Covers (and What It Doesn't)

0 Comments
Travel insurance guide cover showing what policies cover and exclude for US and UK travelers

Short answer

Travel insurance mainly pays for three things: prepaid trip costs you lose when you cancel or cut a trip short for a reason the policy lists, emergency medical bills and evacuation abroad, and smaller losses like delayed or lost bags. It does not pay because you changed your mind, and it routinely excludes undeclared medical conditions, risky activities and trips against government advice. You most need it when you are leaving the US or UK, when your home health cover stops at the border (Medicare and the UK GHIC both have big gaps), or when you have prepaid money you cannot get back.

Last reviewed: September 28, 2026. Rules and figures below are for US and UK residents as of that date. This is general education, not advice on your personal situation.

The decision most travelers face is not "Is travel insurance good?" It is narrower: what could go wrong on this particular trip that I can't afford to pay for myself, and does anything I already have cover it? A weekend drive to see family and a three-week trip to Thailand with a prepaid tour are completely different risks. So are a healthy 30-year-old with an employer health plan and a 72-year-old on Original Medicare.

This guide breaks a policy into its parts, shows where the fine print usually bites, compares card benefits with a standalone policy, and ends with a checklist you can use to compare quotes.

What a travel insurance policy is actually made of

"Travel insurance" is a bundle of separate covers sold together. The US National Association of Insurance Commissioners (NAIC) lists the main pieces as trip cancellation/interruption/delay, baggage loss or delay, travel medical, medical evacuation, and accidental death cover (NAIC, Travel Insurance topic page). UK policies are organised the same way; the Financial Ombudsman Service describes standard cover as emergency medical expenses, cancellation, early return, baggage, delays and missed departures, with personal liability and legal expenses often added (Financial Ombudsman Service).

Each piece has its own limit, its own excess or deductible, and its own list of covered reasons. That is why two policies with the same headline price can pay out very differently.

Trip cancellation and interruption

Cancellation cover reimburses prepaid, non-refundable costs if you can't go. Interruption cover pays when you have to come home early or miss part of the trip. The key phrase is "covered reason." The NAIC gives typical examples: you or a travel companion becoming sick or injured, a family member being hospitalized or dying, severe weather, a natural disaster, or a carrier problem that disrupts the trip (NAIC consumer article, June 2026).

What it won't cover: deciding not to go, a work commitment (unless the policy specifically lists it), or fear of travel that isn't linked to a listed event. The NAIC also flags that buying early matters, because once a storm is named or an event is known, it is no longer "unforeseen" for a new policy.

Cancel For Any Reason (CFAR) is an optional upgrade that removes the covered-reason test, but it is expensive and partial. According to the NAIC, CFAR typically refunds 50% to 75% of the trip price, usually has to be bought within a set time after booking, requires you to insure the full trip cost, often requires cancelling at least 48 hours before departure, and adds close to 50% to the cost of the policy (NAIC). In the UK, look for the specific cancellation reasons in the policy wording; CFAR-style add-ons are less common.

Emergency medical and evacuation

For international trips, this is usually the part that matters most, because a single bad day can cost more than everything else combined.

  • Emergency medical pays for treatment of a sudden illness or injury abroad, and often emergency dental care.
  • Medical evacuation / repatriation pays to move you to an adequate hospital or back home. The CDC's Yellow Book puts the cost of a medevac at about US$25,000 within North America and over US$250,000 from more distant, remote locations (CDC Yellow Book, updated April 23, 2025).

The UK government gives example costs for British travelers: a broken leg in Spain with possible evacuation, £25,000+; a quad bike accident in Greece needing surgery and repatriation, £80,000+; a stomach bug or infection treated in a US hospital with possible repatriation, £150,000+ (GOV.UK / FCDO, Foreign travel insurance).

Two practical points people miss. First, care abroad often has to be paid upfront: the CDC notes that cash or card payment at the point of service is usual and can run to thousands of dollars. A policy with a 24-hour assistance line that can guarantee payment to the hospital is worth more than one that only reimburses you later. Second, in US policies travel medical cover is often secondary, meaning it pays after any other health cover you have (NAIC). Secondary cover still pays, but you may have to file with your own health plan first.

Baggage and travel delay

Baggage cover pays for lost, stolen or damaged belongings and for essentials if your bag is delayed. The NAIC notes it is usually secondary cover, so it pays after the airline's liability and any homeowners or renters policy. Watch the single-item limit and valuables limit; a laptop or camera can easily exceed them.

Travel delay cover pays set amounts or reasonable costs (meals, a hotel) after a delay of a stated number of hours. Before you rely on it, know what the airline already owes you, because insurers expect you to claim from the carrier first. The Financial Ombudsman Service says insurers generally won't cover losses you can recover from an airline or tour operator (FOS).

  • UK: For flights departing a UK airport, or arriving in the UK on a UK or EU airline, the Civil Aviation Authority says passengers can get care (meals, communications, and a hotel if needed) after a delay of 2, 3 or 4 hours depending on distance, a refund option after 5 hours, and compensation of £220, £350, or £260/£520 per person for arrival delays over 3 hours, unless the airline shows extraordinary circumstances such as severe weather (UK CAA, Delays).
  • US: Under the Department of Transportation's automatic refund rule (final rule April 2024), airlines must refund you in the original form of payment if they cancel or significantly change your flight and you don't accept the alternative offered. A significant change includes a departure or arrival more than 3 hours different for domestic flights or 6 hours for international flights (US DOT). A refund gets your fare back; it doesn't pay for the hotel and meals a long delay can cost, which is where a policy's delay cover comes in. Check DOT's refunds page before you travel, as airline consumer rules can change.

The exclusions that sink most claims

Complaints data shows where people get caught out. The Financial Ombudsman Service received 4,466 travel insurance complaints in 2023/24, up 19% on the year before, with rising numbers linked to medical conditions not being properly disclosed, the quality of emergency help abroad, missed or delayed flights, and lost or stolen luggage (FOS news release, July 16, 2024).

Pre-existing medical conditions

This is the single biggest trap, and the US and UK handle it differently.

UK: You are expected to declare conditions when you buy. GOV.UK warns that failing to declare existing conditions, or pending treatment or tests, can invalidate the policy (GOV.UK). MoneyHelper says insurers are likely to treat as pre-existing any condition you're waiting for an operation on or awaiting test results for, any condition you've seen a doctor about in the past year, and any serious condition such as cancer, heart or respiratory problems you've ever had (MoneyHelper). The insurer may then cover the condition for an extra premium, or exclude it.

If an insurer declines you, excludes a condition, or a condition pushes your quote up sharply, FCA rules require the seller to point you to a directory of specialist insurers. From January 1, 2026, the premium trigger is a medical-condition increase of £200 or more (previously £100) (FCA; FCA Handbook ICOBS 6A.4). MoneyHelper runs one of those directories.

Your duty does not end at purchase. The Financial Ombudsman Service says you should tell your insurer about significant health changes during the policy, such as a new diagnosis of a heart condition or cancer, or an urgent specialist referral. The insurer may carry on covering you, charge more, add an exclusion or withdraw cover; if it withdraws cover, it should normally still meet cancellation costs from the date the change happened (FOS, Change in health).

US: US policies usually work with a look-back period: anything treated, diagnosed or showing symptoms within a set window before you bought or booked is excluded. The CDC notes that conditions needing hospitalization or medical intervention in the 90 days before departure are often excluded (CDC). Many comprehensive plans offer a pre-existing condition waiver if you buy within a short time after your first trip payment and insure the full trip cost. The exact window and conditions vary by insurer and state, so check the policy wording rather than a marketing page.

Other common exclusions

  • Risky activities. GOV.UK lists bungee jumping, jet skiing, winter sports, quad bikes and mopeds as things standard policies often exclude; the NAIC gives backcountry skiing and bungee jumping as US examples. Add a sports or winter-sports option if needed.
  • Alcohol and drugs. Most UK insurers exclude events after excessive drinking or recreational drug use (GOV.UK).
  • Travel against official advice. If the FCDO advises against all travel or all but essential travel to your destination, your insurance may be invalidated (GOV.UK). US policies similarly tend to exclude known events and civil unrest.
  • Known or foreseeable events. Buying after a storm is named or a strike is announced usually means that event isn't covered.
  • Pandemics, pregnancy and childbirth. The NAIC lists these among common exclusions; some policies cover pregnancy complications but not normal childbirth.
  • Trip length. Many policies have a maximum trip length, and annual policies limit days per trip (GOV.UK).

What your existing cover already does (and doesn't) do

US: employer plans, ACA plans and Medicare

Some US health plans cover emergencies abroad, but the CDC notes coverage varies (CDC). Call your insurer and ask three questions: Is emergency care abroad covered and at in-network or out-of-network rates? Is evacuation covered? Will I have to pay upfront and claim back? If you want a refresher on how US plans structure deductibles and networks, see our guide to how private health insurance works in the USA.

Original Medicare generally does not cover care outside the US. Medicare's April 2026 fact sheet says it pays for foreign hospital care in only three situations: you're in the US when an emergency happens and a foreign hospital is closer than the nearest US hospital that can treat you; you're traveling through Canada by the most direct route between Alaska and another state; or you live in the US and a foreign hospital is closer to home than the nearest suitable US hospital. Outside those cases you pay the full cost. Medicare plans also can't cover prescription drugs bought abroad, and care on a cruise ship is not covered once the ship is more than 6 hours from a US port (Medicare.gov fact sheet 11037, April 2026; Medicare.gov, Travel outside the U.S.). The CDC adds that Medicare does not cover medical evacuation.

Medigap helps, within limits. Medigap plans C, D, E, F, G, H, I, J, M and N include foreign travel emergency care: they pay 80% of billed charges for certain medically necessary emergency care abroad after a $250 yearly deductible, only if the care begins in the first 60 days of the trip, up to a $50,000 lifetime limit (Medicare.gov). Medicare Advantage plans may cover extra services abroad; Medicare says to check with your plan before you go.

Worked example (hypothetical). Say you have Medigap Plan G, it's your first trip this year, and you need $10,000 of emergency treatment in Italy on day 5. Medigap pays 80% of the amount above the $250 deductible: 80% × $9,750 = $7,800. You pay $2,200, and that $7,800 counts against your $50,000 lifetime cap. It pays nothing toward an air ambulance home, and nothing at all if the emergency starts on day 61.

UK: the GHIC is not travel insurance

The UK Global Health Insurance Card (GHIC) is free and lasts up to 5 years. It gives access to medically necessary state healthcare in EU countries and some others (including Switzerland for certain nationalities, and Australia) on the same basis as local residents. But the NHS is explicit that the GHIC is not a replacement for travel insurance: it doesn't cover private treatment, medical repatriation or mountain rescue, and you may still pay whatever a local resident would pay (NHS, Apply for a free UK GHIC). Apply only through the official NHS service, since the card is free.

Carry both. GOV.UK notes some insurers waive the medical excess if you use your GHIC (GOV.UK). Outside the GHIC countries, including the USA, you rely entirely on your policy. For how the NHS and private medical insurance fit together at home, see our guide to health insurance in the UK.

ATOL, Section 75 and chargebacks (UK)

These protect your money if a travel company fails or doesn't deliver. They do not cover illness or medical bills.

  • ATOL protects package trips that include a flight (and some flight-only bookings) if the travel company stops trading: you get a refund or can finish your trip. The CAA states plainly that ATOL is not travel insurance (UK CAA, About ATOL).
  • Section 75 of the Consumer Credit Act 1974 makes your credit card provider jointly liable for a supplier's breach of contract or misrepresentation when the cash price of an item or service is over £100 and up to £30,000, even if you paid only part by credit card. Chargeback is a card-scheme process available on debit and credit cards, usually within about 120 days (FOS, Section 75 and chargeback). Our guide on how to dispute a credit card charge explains both routes step by step.

Credit card travel protection vs a standalone policy

Many US premium cards include trip cancellation, delay, baggage or travel accident benefits. They can be genuinely useful, but they are usually narrower than a full policy. Look at an actual benefit guide rather than the card's marketing.

Take one example: Visa's published terms for a Visa Infinite trip cancellation and interruption benefit (effective April 15, 2025). It pays up to $2,000 per insured person, but only for non-refundable common carrier tickets (air, rail, ferry, bus, cruise fares), not hotels or tours. You must charge the entire fare to the card or its rewards program. Covered reasons are limited to death, accidental injury or physical illness of you or an immediate family member, verified by a doctor, or the carrier going bust. Pre-existing conditions are excluded, defined with a 60-day look-back before booking (Visa, Trip Cancellation and Interruption terms). Visa notes benefits vary by issuer and card. There is no emergency medical or evacuation cover in that benefit.

In the UK, travel insurance bundled with credit cards is less common; it more often comes with packaged bank accounts. Treat those the same way: check age limits, trip-length limits, and whether you have to declare medical conditions separately. When you're choosing a card for its travel perks, our guide on how to choose the right credit card explains how to weigh benefits against fees and rates, and our explainer on foreign transaction fees and DCC covers the other cost of using a card abroad.

What you need Typical card benefit (US) Comprehensive standalone policy Public schemes (Medicare / GHIC)
Cancellation of prepaid costs Often fares only, capped (e.g. $2,000 per person in the Visa Infinite example); narrow reasons All insured prepaid costs, wider list of reasons; CFAR optional (US) None
Emergency medical abroad Usually not included in standard benefits; check your card Yes, up to policy limit; may be secondary in the US Medicare: rarely. Medigap: 80% after $250, $50,000 lifetime. GHIC: state care in listed countries only
Evacuation / repatriation Varies; many cards don't include it Yes, up to policy limit Not covered
Pre-existing conditions Usually excluded (look-back applies) US: waiver if bought early. UK: covered if declared and accepted GHIC covers ongoing care for chronic conditions within its rules
Cost to you Included in the card (annual fee may apply) US: NAIC says typically 5%–10% of trip price GHIC free; Medigap premium already paid

Do you need travel insurance? A quick way to decide

Work through these four questions in order.

  1. Where are you going? Leaving the country is the big dividing line. For US travelers, Original Medicare and many health plans stop at the border. For UK travelers, the NHS doesn't follow you, and the GHIC only works in certain countries and only for state care. A trip to the USA is the high-cost case for UK residents; GOV.UK's example is £150,000+ for an infection and repatriation.
  2. What would you lose if you cancelled tomorrow? Add up everything non-refundable: flights, deposits, tours, cruise fares. If the answer is small or fully refundable, cancellation cover adds little.
  3. What do you already have? List your health plan's foreign cover, Medigap or Medicare Advantage, GHIC, card benefits and any packaged bank account policy. Note the gaps, especially evacuation.
  4. What's unusual about this trip? Skiing or diving, a remote destination, a long trip, a pregnancy, an elderly relative whose health could force a cancellation, or your own medical condition all change what cover you need.

Worked example (hypothetical). Say a US couple book a $4,000 non-refundable tour in Portugal. Using the NAIC's 5%–10% range, a comprehensive policy might cost roughly $200 to $400. Adding CFAR could add close to 50% to that premium, and would then refund 50%–75% of the trip, or $2,000 to $3,000, if they cancelled for a reason the base policy doesn't cover. Whether that's worth it depends on how likely a non-covered cancellation is and how much a $4,000 loss would hurt. Your actual quote will depend on age, destination, trip cost and state.

How to compare policies

Price comparisons are only meaningful after you've matched the cover. Use this checklist on the policy wording (not the summary page):

  1. Medical and evacuation limits. Is emergency medical primary or secondary? Is evacuation to "nearest adequate facility" only, or home?
  2. 24-hour assistance. GOV.UK and the CDC both point to a round-the-clock helpline; the CDC also suggests checking whether the insurer pays hospitals directly.
  3. Covered reasons for cancellation. Read the list. Is a family member's illness covered? Work reasons? Airline strikes?
  4. Medical declarations or look-back. UK: declare everything the questions ask about. US: note the look-back period and waiver deadline.
  5. Excess or deductible per claim and per section, and whether it's waived for GHIC use.
  6. Baggage single-item and valuables limits, and receipts required.
  7. Activities and destinations. Is your sport included? Does the policy's geographic zone include the USA?
  8. Trip length and, for annual policies, maximum days per trip.
  9. Cooling-off or free-look period. In the US, these are set by state law and vary, so check with the insurer or your state insurance department.

Buy as soon as you've booked. GOV.UK recommends buying as soon as possible after booking, and the NAIC notes early purchase avoids weather-related denials and keeps US time-limited options like CFAR and pre-existing waivers available.

When this doesn't apply

  • Short domestic trips with refundable bookings. If your home health cover works where you're going and nothing is prepaid, standalone travel insurance often adds little.
  • Long stays, study abroad or moving overseas. Standard travel policies have trip-length caps and are designed for holidays. Look at international health insurance or student plans instead. (Driving? See our note on car insurance for international students in the USA.)
  • Business trips. Your employer may already cover you under a corporate policy; ask before buying.
  • Visitors to the US or UK. This guide is for US and UK residents. Inbound visitors have different rules and products.

FAQ

If my claim is rejected, what can I do?

UK: complain to the insurer (or the broker you bought from). If you don't get a final response within 8 weeks, or disagree with it, you can take it to the Financial Ombudsman Service for free. US: complain to the insurer in writing, then to your state insurance department; the NAIC directs consumers to their state regulator.

Does travel insurance cover a missed connection?

Often, but only under the policy's own terms. The Financial Ombudsman Service lists missed departure among standard UK cover, and many US plans have a missed-connection section; both usually require the cause to be a listed event, such as a carrier delay or an accident on the way to the airport. Check the minimum delay and whether you left enough time; claim from the airline first.

Is annual multi-trip cover cheaper?

It can be if you travel several times a year, but check the maximum days per trip and whether cancellation limits suit your most expensive trip.

Should I declare a condition I think is minor?

Yes, if the insurer's questions cover it. MoneyHelper's advice is not to assume something is covered and to ask the insurer. Undisclosed conditions are a leading reason for rejected claims in Financial Ombudsman data.

Can I rely on my credit card's cover alone?

Only if you've read its benefit guide and it matches your trip. Many card benefits cover fares but not hotels or tours, and many have no emergency medical or evacuation cover. Watch for policies that require you to pay the whole trip on the card.

Bottom line

Travel insurance earns its cost when a trip combines one of three things: money you can't get back, medical care your home cover won't pay for, or risk your existing cover excludes. Medicare and the GHIC both leave large gaps abroad, especially for evacuation, and card benefits are usually narrower than they look. Your next step: list what you already have, identify the gaps for this specific trip, then compare two or three policies using the checklist above, reading the medical and exclusions sections before the price. If you're financing a trip on a card, it's also worth reading why credit cards can become a financial trap before you book.
