Most people buy travel insurance the way they buy a SIM card at the airport, quickly, without reading it, and hoping never to need it. That approach works for a data plan. It does not work for insurance, because the gap between what people assume a policy covers and what it actually covers only shows up at the worst possible moment, in a hospital in a country where you don’t speak the language.
Start with the number that matters most for Europe. If you are applying for a Schengen visa, your insurance is not optional and it is not flexible, the policy must show a minimum of 30,000 euros in medical coverage, valid across all Schengen countries for the entire length of your stay, with repatriation included. This is a legal requirement under EU regulation, not a recommendation, and consulates reject applications over it regularly. A policy that covers less, or one that only covers the specific country you’re visiting rather than the whole Schengen area, will get flagged.
Outside the Schengen zone, insurance stops being a visa requirement and becomes a judgment call, which is exactly where people cut corners. The most common gap is pre-existing conditions. Standard policies exclude them by default, so if a parent with diabetes or a family member with a cardiac history is travelling, that exclusion needs to be declared and covered explicitly, usually at a higher premium, or it isn’t covered at all. The second common gap is adventure activities. Trekking, diving, skiing, and similar activities are frequently excluded from base policies and need an add on rider. A caving trip in Vietnam or a trek in Sapa, both entirely reasonable things to do on holiday, can fall outside a standard policy’s fine print without anyone realising until a claim is filed.
The third gap is the one nobody thinks about until it happens, trip cancellation and interruption. If a flight gets cancelled and the connecting leg is missed, or a family emergency cuts a trip short, cancellation cover is what gets the unused, non-refundable portion of the booking back. Baggage delay and loss cover is smaller money but genuinely useful, most policies pay out a fixed amount if checked baggage doesn’t arrive within a set number of hours, enough to buy essentials while it’s traced.
What actually matters when comparing policies is not the headline premium, it’s four numbers, the medical coverage limit, the pre-existing condition clause, whether adventure activities are included or need a rider, and the cancellation limit relative to what has actually been paid for the trip. A cheap policy with a 30,000 euro medical minimum and no adventure rider is not a good deal for a family doing a trekking and caving itinerary, it is a policy that technically satisfies a visa requirement and covers almost nothing else.
Buy insurance after the itinerary is finalised, not before, so the policy can be matched to what the trip actually involves rather than a generic international plan. And buy it directly through the insurer or a broker rather than as an unread add on at checkout, five extra minutes reading the exclusions is the difference between a policy that works and one that only looks like it does.
