A vacation is a great way to relax, but to ensure that the trip is entirely stress-free, one should buy travel insurance. This is crucial, especially if vacationing abroad, because while existing insurance may cover domestic travel-related issues, the policy may be invalid abroad. Also, it is equally important to find an insurance policy that adequately covers health and other issues while traveling abroad. To do that, one must avoid certain mistakes while buying insurance. 1. Waiting till the last minute The most common mistake when planning an overseas trip is waiting till the last minute to buy insurance. When one gets travel insurance closer to the trip, they are likely to not have enough time to find the ideal option. For instance, one might have to settle for a plan that does not come with cancellation coverage, as one would be purchasing the policy a few hours before their flight. Also, last-minute travel insurance may not offer coverage for issues on trips caused by pre-existing health conditions. While buying earlier might not mean better coverage, it does give one enough time to shop around for the best options as per their preferences. 2. Buying insurance on the trip If one has forgotten to buy travel insurance before the trip and do it while they are already abroad, the policy they get might be void, and one might not be able to make any claims.
