Folks,
I just joined so that I could reply to this thread. Any news on this situation? A few months ago I found Avios availability from Memphis-Madrid via Iberia no problem. Now, no matter the date range entered I get the "We have not found outbound flight conforming to the criteria specified. Please change the selection and try again. (9100)"message. I want to book via Iberia to fly on AA rather than booking with British Airways due to the obvious difference in fuel surcharge and tax fees. I speak Spanish, so I might have more luck calling the Customer Service agents.
Thanks in advance for your responses.
