Good, if you have one, these insurances are no longer very expensive these days, so every traveler should always consider this on ALL trips he / she takes.
Do you have an insurance that covers or partially reimburses your costs in the event of cancellation? Please contact the respective insurance company, because you have to report your resignation there like a loss. You will usually have to fill out a form and then your case will be assessed.
Unfortunately, we cannot contact the insurance company on your behalf. This has a legal background and we ask for your understanding.
