Ex-CAI route change info only. As prev posted I was originally on a QF issued ticket and able to get AA to take it over - thank goodness!. Anywhoo for anyone interested who is on an AA issued ex-CAI ticket I was forced to make changes to my routing yesterday as I called to push out my SEA-DFW-SCL sector and discovered that AA are discontinuing the route from end of March. This forced a change to SEA-MIA-SCL. I have not yet flown the first sector so the agent suggested a $125 change fee was likely and "possibly" a reprice if the fare had changed. This was obv concerning but since AA do not have a published XONEX fare out of CAI any longer I was prepared to wait and see - well good news is they came back today with the fee and it was just the $125 change fee. So it would appear that for at least some route changes a reprice wont happen on ex-CAI XONEX's of course YMMV. I'm not sure about taxes as don't know if a change between DFW and MIA would have seen any additional taxes/carrier charges under any circumstances (I assume adding a stop like LHR or CDG must incur an additional tax fee on top of the $125 at minimum)
