Yes, of course you can make changes if the ticket is changeable. \For example, if you booked with an old passport number because it was being renewed, you can contact us to change it before your departure date. You can also change your departure date or accommodation, but please note that rates may vary according to dates and availability. With regard to cancellation, you may be entitled to a refund, but this depends on the shipping company and the specific conditions linked to the date of your cancellation request. We recommend that you send your request by e-mail to info@bladia.com at least 48 hours before departure to ensure efficient processing.
