Service fees cover the costs incurred by Travelden in booking and servicing your travel reservations. In the event of the client cancelling a booking, Travelden shall have the right to either claim an amount or to retain an amount of the payment as cancellation fees payable to Travelden. We will not provide a refund to you until we receive the funds from the relevant supplier. Cancelled bookings may incur charges directly from the supplier. These charges can be up to 100% of the cost of the booking, regardless of whether travel has commenced. Where we incur any liability for a cancellation fee or charge for any booking which you cancel, you agree to indemnify us for the amount of that fee or charge. An amendment fee per booking may be levied for any changes to the confirmed itinerary and or ticket. This is charged in addition to the change fees charged by the supplier and other Third Party Service Providers. In the unlikely event of there being an unscheduled extension to the final itinerary caused by flight re-scheduling, flight delays, bad weather, strikes or any other cause which is beyond the control of Travelden, its agents or suppliers, it is understood that expenses relating to these unscheduled extensions (hotel accommodation etc.) will be for the client's account. While every effort is made to keep to the final itinerary in accordance with the client?s application, our suppliers and/or Travelden reserve the right to make changes intended for the client's convenience e.g. in some cases, weather conditions can necessitate an alteration in the itinerary and this does not constitute any reason for a refund. It is the client's duty to check each amendment to the itinerary.
