I have recently received word that Iberia has cancelled a flight which was to be flight 19 of 20 on a CAI-issued DONE5. The coupon on the ticket was dated for 4/24.
My original booking was ...GIG-BCN-CAI, with the stop in BCN being less than 24 hours as I have used up my two permitted stopovers in the continent of origin. The following were the details on my last two flights:
#19 - IB6806 - GIG-BCN 4/24, arriving mid-morning on 4/25 (incidentally, this flight was ticketed on one coupon, but on the itinerary provided by EMECO there is a note printed on the line immediately following this flight which reads “CHG-EQ MAD MUST ADV CUSTOMER”. One World still has the flight in their online schedule. I know this doesn’t mean that it is still available, but it corroborates the fact that this flight existed on one # even if there was a change of equipment in a connecting city.)
#20 - IB6974 - BCN-CAI 2/25, leaving early-evening.
Flight IB6806 is the flight which has been cancelled. With the latest printout as provided by QF, it appears that IB have protected me from GIG to MAD leaving on 4/25, but on a flight which is scheduled to leave GIG fifteen minutes before my flight is due to depart from BCN on 4/25!
I have contacted AA RTW in Dallas. AA has offered to fly me GIG-LHR-CAI. (I am not sure if the agent that I spoke with noticed that I have already flown my two allotted Eur/ME flights which were LHR-DXB-LHR.) I am due to be in BCN the afternoon of 4/25, so GIG-LHR-CAI doesn’t work for me. The AA agent then told me to contact IB. IB told me that they have protected me as far as MAD (which as stated earlier, I can see on my itinerary). They don’t fly GIG-MAD on 4/24, but have flights on 4/23 & 4/25, but since the single flight number GIG-BCN doesn’t exist anymore, they can’t protect me beyond MAD because it is a promotional fare.

They say that I have to contact AA as AA has issued the ticket and it’s up to AA to set it right.
AA says call IB. IB says call AA.
Can I get some advice from those more familiar with the details of the xONEx product to tell me if I can request IB to fly me to BCN on 4/23, even if it’s on two flight #’s using my one GIG-BCN flight coupons, and still keep my flight to CAI on 4/25?
