6.5 Coupon Sequence
(a) The fare paid for your Ticket has been calculated on the basis of the sequence of transportation shown in your Ticket.
(b) Once travel has commenced, if you do not wish to continue the journey in that sequence, you must pay any applicable fees, taxes and fare adjustment. The Ticket will be reissued for the new fare which will be the full unrestricted fare that was applicable for the relevant class of travel on the date of original purchase for the revised itinerary.
(c) Alternatively, you may request a refund for the unused portion of your Ticket within 12 months after the original date of Ticket issue. The amount to be refunded (if any) will be the difference between the fare paid and the full unrestricted fare that would have been payable for the revised itinerary. Any applicable change fee and service fee will be deducted from that amount.
(d) If you wish to change to your sequence of transportation before travel has commenced, and your fare rules allow it, you may request a fare recalculation and ticket reissue, in which case payment of any applicable fees and fare difference will be required.
