How does travel insurance work? Travel insurance is an optional addition to your total rental charges. It is offered on our reservation form at the time of booking. It is also usually offered at the time of booking when you booked with a 3rd party booking site. You can also add travel insurance onto your reservation within 48 hours of booking with SkyRun. The cost of travel insurance varies and is usually between 7% – 9.5% of your total reservation cost depending on the coverage type. If you do not have travel insurance, you can not cancel your reservation for any reason. If you have travel insurance and need to cancel or make a claim, please refer to your specific policy.
