5 Travel Insurance Mistakes That Can Cost You Thousands

By Mike Harper · June 18, 2026

Travel insurance is one of those products most people buy hoping they’ll never use — and then discover the limitations only when they try to file a claim. The mistakes below are the ones that consistently result in denied claims and unrecovered costs.

1. Buying it too late

Most travel insurance policies must be purchased within 14 to 21 days of your initial trip deposit to qualify for the full range of benefits — including the “cancel for any reason” upgrade and pre-existing condition waivers. If you buy insurance the week before departure, you typically lose access to both. The coverage still exists, but it’s narrower than what was available at the time of booking. Buy within two weeks of your first payment.

2. Assuming your credit card covers everything

Many premium credit cards include travel insurance as a cardholder benefit — but the coverage is almost always secondary, meaning it only kicks in after your primary insurance has paid. Credit card trip delay coverage typically caps at $500. Trip cancellation coverage is often limited to specific scenarios like severe weather or airline bankruptcy. Read your card’s benefits guide before assuming it replaces a standalone policy. For most travelers, it supplements but does not replace.

3. Not understanding what “cancel for any reason” actually means

Cancel for any reason coverage — typically abbreviated CFAR — is the most flexible cancellation benefit available. It allows you to cancel your trip for literally any reason and receive a reimbursement. But it usually reimburses only 50 to 75% of your non-refundable costs, not 100%. And it must be purchased within that 14 to 21 day window after your first deposit. Most travelers who think they have CFAR coverage don’t — because they bought the policy too late to qualify.

4. Not reading the pre-existing condition clause

If you have a medical condition that was diagnosed, treated, or had symptoms within a lookback period — typically 60 to 180 days before purchasing the policy — claims related to that condition may be denied. A pre-existing condition waiver removes this exclusion, but it is only available if you purchase coverage within the early purchase window and insure the full cost of your trip. If you have any ongoing health condition, this waiver is the single most important feature of your policy.

5. Filing a claim without documentation

Travel insurance claims require documentation. A flight cancellation claim requires the airline’s written confirmation of the cancellation and the reason. A medical claim requires receipts, doctor’s notes, and proof of payment. A theft claim requires a police report filed within 24 hours. Travelers who experience a covered event but don’t collect documentation in real time frequently have their claims denied months later because they can’t prove what happened. The moment something goes wrong on a trip, start documenting. Take screenshots of airline notifications. Get written confirmation from hotels. File police reports immediately.

The best travel insurance is the kind you buy early, understand fully, and hope you never need. The worst is the kind you buy late, assume covers everything, and discover doesn’t when you try to use it.
