If you're wondering when you should buy travel insurance, the simple answer is, “as soon as possible.” Ideally, you'll buy coverage no later than 15 days prior to your trip.

In 2026, the "Golden Rule" for travel insurance is to purchase a policy within 10 to 14 days of making your first trip deposit. While you can buy insurance up until the day before you depart, purchasing it early unlocks critical "time-sensitive" benefits that are unavailable later. These include Pre-Existing Condition Waivers, which ensure medical issues are covered, and Cancel For Any Reason (CFAR) upgrades, which allow you to claw back 50–75% of your costs for any non-covered reason. If you wait until a storm is named or a pandemic is declared, you cannot buy coverage for those specific events. For frequent travelers, 2026 trends favor Annual (Multi-Trip) plans, which can be purchased at any time but must be active before a trip is booked to cover cancellations. Essentially, the moment you put money down that you cannot get back, you should secure your insurance to protect that investment from unforeseen life events or global disruptions.
