Best travel insurance for families

This is not insurance advice. It’s a guide to what to compare, written by someone who reads policy wordings for fun. Cover differs by your country of residence and changes often. Read the actual policy document, and if your family’s situation is complicated, talk to a licensed broker.

Family travel insurance goes wrong in predictable places. Not the headline medical limit (most policies have a big number there), but the small definitions: who counts as a “child”, whether your daughter’s asthma is a “pre-existing condition”, and whether a grandparent’s hospital stay lets you cancel. Here’s how to check those before you pay.

Who counts as family?

Every insurer defines it differently, and the definition decides whether your teenager is on the policy.

• World Nomads’ US family plan covers one or two adults aged 69 or under plus up to seven dependent children under 25. Everyone must be a US resident, live in the same state, and travel on the same itinerary, and at least one adult must be the children’s legal guardian. There’s a maximum of nine travellers per plan.
• Allianz says its OneTrip Prime and OneTrip Premier plans cover kids 17 and under for free when they travel with a parent or grandparent, except on policies issued to Pennsylvania residents.
• SafetyWing lets you add a spouse or children at sign-up, and says children’s plans cost up to 35% less than adult ones. Its price calculator uses separate age bands for under-18s, so check the quote for your children’s ages rather than assuming a flat rule.

What to look for: the maximum child age, whether “dependent” means financially dependent, whether kids have to travel with you every day of the trip, and whether a grandparent counts as an eligible adult.

The pre-existing condition clock

This is where families get caught out, because “pre-existing” usually covers more than you’d think. Allianz, for example, uses a look-back window of 120 days before and including the purchase date: if anyone on the policy saw a doctor, had symptoms or took prescribed medication for a condition in that window, it counts. SafetyWing’s Nomad Insurance Complete doesn’t cover pre-existing conditions at all, and defines them broadly. World Nomads says pre-existing conditions generally aren’t covered unless specifically included.

Some US policies let you get round this with a waiver, but only if you buy early.

Allianz’s version, for example, requires you to buy within 14 days of your first non-refundable trip payment, be medically able to travel on purchase day, insure your full non-refundable trip cost and be a US resident. The practical lesson works almost everywhere: buy insurance the week you book, not the week you fly.

Cancellation is a different product

For a lot of families the likeliest loss isn’t a hospital bill but a trip that doesn’t happen: a child gets chickenpox, a school changes term dates, a grandparent falls ill. Whether you’re covered depends on what kind of policy you bought.

• Trip insurance (Allianz’s OneTrip plans, World Nomads’ Standard and Explorer plans for US residents) includes trip cancellation for covered reasons. “I changed my mind” is never one of them.
• Travel medical / nomad insurance such as SafetyWing is built around medical cover. Nomad Insurance Complete’s cancellation cover is small: US$300 per trip and US$600 per year at the time of writing. That’s fine for a long open-ended stay and not much use for an expensive booked holiday.
• A relative at home can trigger a cancellation claim even though they aren’t on the policy. Allianz notes the “medically able to travel” requirement applies only to the people named on the plan, but cancellation claims linked to a pre-existing condition can carry a lower sublimit (on OneTrip Prime, US$50,000 per person against US$100,000 for other cancellations). Check whose illness counts and at what limit.

Three providers side by side

	World Nomads Partner	SafetyWing Partner	Allianz Travel (US)
Best fit	A booked trip with activities	Long or open-ended stays	A booked US-resident family holiday
Children	Up to 7 dependants under 25 (US plan)	Added at sign-up, priced by age band	Kids 17 and under free on OneTrip Prime/Premier (not PA)
Adult age limit	69 or under (US family plan)	Sign up until 64 (Complete)	Check plan
Pre-existing	Generally not covered unless included	Not covered (Complete)	Waiver if bought within 14 days of first payment
Trip cancellation	Yes, covered reasons	Small sublimit	Yes, covered reasons
Adventure activities	150+ listed activities	Check policy	Check plan

World Nomads is the stronger choice for a fixed trip with an active streak (it lists 150+ covered activities). SafetyWing is designed for people who are away for months, so it suits families on a sabbatical or worldschooling year more than a two-week beach holiday; our nomad insurance guide goes further into that. Allianz is a non-partner, and for US families on a booked holiday the free-kids rule and pre-existing waiver are genuinely good features.

If you’re travelling from the UK

A free UK Global Health Insurance Card gets you state healthcare that can’t wait until you’re home in EEA countries and a few others such as Australia, including care for pre-existing conditions. Every family member, children included, needs their own card. The NHS is blunt that it’s not a replacement for travel insurance: it doesn’t cover medical repatriation or mountain rescue. Carry both.

Six questions before you click buy

1. What’s the maximum child age, and does a 19-year-old at university count?
2. Does every family member need to be on the same itinerary every day?
3. What counts as pre-existing, how far back does it look, and is there a waiver window?
4. Whose illness lets you cancel: only travellers, or close relatives too?
5. What’s excluded for kids’ activities (ski school, snorkelling, horse riding)?
6. Is it priced per person, per family, or with free children, and does that change with the destination?

Write the answers down. If an insurer’s website can’t answer them clearly, its policy document will, and reading it once is cheaper than learning it at a claims desk.
