Travel insurance, explained: what it covers, what it never covers, and how to buy it well

Travel insurance is the policy people buy least thoughtfully — a tick-box at checkout — and the one whose exclusions bite hardest, because it is claimed at the worst moment of a trip. Ten minutes of understanding buys a materially better outcome.

What it actually covers

The product bundles several distinct protections. Emergency medical is the core and the reason to buy: treatment abroad can cost tens of thousands, and your domestic health cover typically travels poorly or not at all — including evacuation home, the single most expensive line in travel claims. Trip cancellation and curtailment reimburses prepaid costs when you cannot travel or must return early for covered reasons — illness, bereavement, sometimes redundancy; note the covered-reasons list is narrower than intuition. Baggage, delay and personal liability round it out at smaller limits. For trips where medical care is reciprocal or cheap, the policy is mostly about cancellation; for anywhere else, the medical block is the entire product.

The exclusions that bite

Four exclusions generate most disputes. Pre-existing medical conditions — undeclared conditions void related claims, and "declared" means answering the medical questionnaire honestly even when the questions feel intrusive. Alcohol — incidents while intoxicated are excluded nearly universally, and adjusters do ask. Unattended belongings — bag snatched from a café chair is not theft in policy language. And disregarded government advice — travel against official advisories voids most of the policy. The pattern: travel insurance covers misfortune, not misjudgement — the same underwriting philosophy that prices every policy, per the premiums explainer.

How to buy it well

Three moves. Check overlap before buying: premium bank accounts and credit cards frequently bundle travel cover — buying a duplicate policy is the most common waste in the category; read the bundled policy's limits, though, because card cover is often thin on medical. Buy early: cancellation cover only protects against events after purchase — buying the day before departure means the month of prepaid risk was never covered. Annual multi-trip for two-plus trips a year: usually cheaper than per-trip, with one discipline — check the maximum trip length, commonly capped around 30 days. And size the excess sensibly against baggage limits, the same arithmetic as the deductibles guide.

The honest summary: travel insurance is emergency medical cover with cancellation protection attached — valuable when the medical exposure is real, largely redundant when it is not. Declare your conditions, buy before the risk starts, check the card in your wallet first, and read the exclusions once, now, while the trip is still a pleasure to think about.
