When to Buy Travel Insurance: Timing That Actually Matters

"I'll buy it closer to the trip' is one of the most common — and costly — assumptions in travel planning. Two specific coverages are directly tied to how early you buy.

Pre-existing condition waivers

As covered in our pre-existing conditions guide, most waivers require purchase within a set window (often 14-21 days) of your initial trip deposit — miss that window and the waiver typically isn't available at any price.

Cancellation coverage starts at purchase, not departure

Trip cancellation coverage only protects against reasons that arise after you buy the policy. If you wait to buy until a week before departure, anything that happened before that date isn't covered, even if it later prevents your trip.

The practical rule of thumb

Buy within a few days of paying your first trip deposit — that single habit captures both the pre-existing condition waiver window and the earliest possible cancellation coverage start date.
