Trip cancellation insurance is a type of coverage that reimburses travelers for non-refundable expenses if they need to cancel their trip due to unforeseen circumstances. This can include reasons like illness, injury, or a family emergency. It helps protect your investment in travel arrangements, such as flights, hotels, and tours. When purchasing trip cancellation insurance, it's important to read the policy carefully to understand what is covered and any exclusions. Some policies may also offer additional benefits, like coverage for trip interruptions or delays. Always compare different plans to find the one that best suits your travel needs.
