As with all insurance, the devil is in the policy details so be sure to read closely what is covered and what is not so you are not surprised if you do have to file a claim. Pre-existing conditions and what constitutes a travel delay/interruption seem to be two things that surprise people. Insuremytrip and SquareMouth are two sites you can compare different plans and companies.
