Subject: Trip insurance

I am planning a trip to India and Bangladesh in January. It has recently occurred to me that I should probably have trip insurance...something to protect my ticket investment in case anything causes a cancellation. I don't worry about my health...mainly world events and weather. I was off the list for a few months but when I signed back on I think I saw that you all discussed insurance? The list isn't archived...could anyone sum up the discussion? Where do you get it...what should I be on the alert for in purchasing insurance etc... Any help would be appreciated Joan Malden Bridge
