Any cancelation must be submitted formally in writing. Cancelled bookings may also incur supplier fees, which can be up to 100% of the cost of the booking, regardless of whether travel has commenced. Supplier fees may also apply where a booking is changed and when tickets or documents are re-issued. Where we incur any liability for a supplier cancellation fee for any booking which you change or cancel, you agree to indemnify us for the amount of that fee. Where you seek a refund for a cancelled booking for which payment has been made to the supplier, we will not provide a refund to you until we receive the funds from that supplier.
