If it's through Allianz, I wouldn't bother. I used them for travel insurance once and will never use them again. They make you jump through a million hoops to file a claim, I had to keep contacting them to process my claim only to find out they needed yet another supporting document, and in the end they denied the claim because, according to the policy, "terrorism and acts of war" were not valid reasons for canceling a trip. Maybe it's different for things like show/concert tickets, and I suppose if the insurance is pretty cheap, it's not a big deal, but be aware that filing a claim can be more of a hassle than it's worth and you need very specific, valid reasons for doing so. If I wasn't able to use my tickets to a show, I would rather go through the process of trying to sell my tickets instead, even if I ended up losing some money in the deal.
