You fell into a common trap about trip cancellation, delay and interruption policies — assuming that this coverage will pay for anything that is truly not your fault. But claims adjusters tend to be extremely literal in interpreting the fine-print list of “perils” or “hazards” your policy covers....

Three of the seven plans I looked at — Norwegian, Royal Caribbean and Princess — leave airline issues out of trip interruption benefits entirely, making it impossible, in a situation like yours, to claim the value of a missed cruise in its entirety....The other four cover delays to varying extents. Carnival mentions only weather issues. MSC and Viking cover mechanical problems, weather delays and strikes — pretty standard language, but not all encompassing. Only Disney’s plan allows trip interruption to kick in for “any delay of a common carrier,” as long as it causes you to miss at least half the trip.
