Recommendations for flexible booking/Cancellation
Please always try to book accommodation or tickets with a flexible or at least partly refundable/rebooking option (with fees). The university is unlikely to pay for travels that have not taken place, but supports the fees for rebooking/refunds if the travel was considered necessary.
To make sure you are safe, it is best to take out travel insurance for travels before the travels. The insurance provider will pay most of the expenses if you get sick and will also ensure your safe transport back home.
If you want to be sure to get your money back when cancelling non-refundable things, take out cancellation insurance (Reiserücktrittskostenversicherung). Some travel insurance packages come with this as well.
