Yes, you can purchase travel insurance right up until you leave for your trip – even in the airport departure lounge. However, there are advantages to purchasing travel insurance when you’re paying for your vacation. Additional features, such as the Cancel for Any Reason benefit. This allows you to cancel your trip due to an unforeseen covered reason up to three hours before departure. You’ll receive a refund of up to 50 percent from any prepaid non-refundable charges. And, if you booked your trip with CAA Travel, you’ll get up to percent back. For the full list of eligible reasons covered by CAA’s Trip Cancellation and Interruption Insurance, please read our Travel Insurance Policy Guide.
