Once I have a J partner award ticketed (DCA-JFK-ZRH(stopover)-PRG(destination)-ZRH-MIA-DCA), can I change the routing of the return and add a stopover in Canada? For example, would changing the ZRH-MIA-DCA to ZRH-YUL(stopover)-DCA be allowed? I assume that this would be allowed if there were a non-stop between YUL and DCA, but there is not so I would need to connect in ORD, which would add another segment to the ticket.
Thanks.
