If you travel quite often, we strongly suggest buying an annual plan. Another way to determine whether to choose single trip or annual travel insurance is by comparing the price you would have to pay through the course of the year if you were to buy single trips, versus the price of the annual travel insurance. If annual travel insurance is more cost-effective, it might be the better choice.
Kindly note that annual travel insurance has a maximum coverage period of 90 days per trip. If your trip exceeds more than 90 days, you will need to purchase a single trip insurance for the entire duration of that particular trip.
